Actually, I've known this for a while but first time guests may not...
Take for instance this past Saturday night at the California Grill. My GF and I were having dinner in the Wine Room when we see this woman start fighting with anyone within earshot who works there. Basically, she said she had "Reservations" at 7:15... She got there with her group at 6:45 and was still not seated and now it was 7:30...
Now, I can understand if this was a party of 4... But this was a party of 14!!!!!! You have GOT to understand that even with Reservations...it is not easy to snap your fingers and there you go...table for 14... Unfortunately, the CMs caved in and sat this group...5 adults, 9 kids...in the Wine Room, where kids were not supposed to be... It did not ruin my time but me and my GF felt awful for the Servers... We kidded with them often about the situation...and even got a "can't wait until 10 PM" from them...
Goes to show you have to understand the situation before making one yourself...
