I've got a couple.
First was at the Blue Lagoon. It's the restaurant inside the POTC ride at DLP. We had made an 8 pm ADR (park closes at 9), we check in, I ask if we can get a waterfront table, and the hostess says she'll see what she can do and asks us to wait. After some time, she calls our name, gies us a piece of paper and says we can go to the "bridge". This is the part of the restaurant where they take that piece of paper, ask what language you speak (for the right menu) and seat you.
I ask the girl there if we have a waterfront table, and she just says NO and asks us to follow her. There are plenty of free tables with a nice view of the passing boats, but no, she takes us all the way to the back of the restaurant, where it's even more dark than at the other tables. She seats us at a table that is partially on some stairs, that has no candle (this is a dark restaurant!), only one fork and one knife, no napkins, ... There is no one seated at the other tables around, and those tables are better placed. After waiting for half an hour, I am so angry (and hungry) that we just pick up our stuff and leave! But first I complained to the hostess.
What had happened? The hostess had written a table number on the paper, but the girl had seated us at another table in a closed section of the restaurant. She offered us another table but we just left. By that time, it was already 8.45, and we had no ADR at another restaurant. At DLP, you don't really need ADRs, you can have TS dinners without them, but then you have to wait a long time, especially when the park closes and everybody heads to teh restaurants. We ended up eating at planet Hollywood that night!
Another one: I was shopping, and I knew that there was a special Lancome event going on at Ici Paris XL (a perfumery chain, like Sephora). If you bought a couple of items, you received a free bag with travel sized products. So, I enter one of their stores. There are 3 customers (including me) and 7 sales people. When I ask one of them for advice on what colour of eyeshadow I should get, she asked me if I had an appointment. Euhm... no, I haven't. No way to get advice without having an appointment

I left the that store, and went to another Ici Paris XL further down the street. I never went back to the first one afterwards!
ANother one: I was doing some serious shopping at WE (a store somewhat comparable with Banan Republic or so). Anyway, over here, the sales people will never offer to hold your clothes in a fitting room,a dn after trying stuff on, you have to put it back in the store yourself.
OK, so we are virtually alone in the store, and for the first time ever, there are many many items I like and want to try. So I arrive at the fitting rooms with about 15 items. Nope, am not allowed in, 7 piece maximum. OK, I do understand that rule during the weekends or when teh store is very busy, but there was no one there!!! No way to take all the clothes in the fitting room. So, my mom grabs half of them,a dn my brother one item, and then we can go, bevause we each have maximum 7 items. Nevermind my brother is holding a dress in his hands.
So, I try teh clothes on, decide to buy about all of it, and we go back in the store, and I see some additional items I would liek to try on. Once again, the girl at the fitting rooms makes a drama because of the fact that I have all those other items. And no, they don't want to hold them at the register. I have no idea how you are supposed to buy more than 7 items in that store if you're by yourself, other than paying after 7 items, and continue shopping.
This was an option that I didn't want. I had coupons, for every 25 EUR spent, i got 5 EUR off, so the best deal is to add everything up, and then get the reduction on the grand total.
Anyway, that was the last time I shopped at that store.
