I think I got a handle on the diffference between TS and CS. But just to clarify in my mind. Pretty much all CS is walk up (like at the resorts) and TS is actually being seated by someone. I am saving up 2TS credits for CRT the last day we are there, so I am worried about accidently using a TS credit for something. And a snack credit for CS.
Is everything pretty much clearly marked as to what is a SC and CS... am I just looking too much into this??? lol
It is probably next to impossible to use up a TS credit accidentally. Buffets (like Boma, Crystal Palace, etc) are all counted as TS. There is at least one CS where you are often seated and it has waiters and that is Wolfgang Puck Express, however, it counts as a CS credit only!
Most counter service places (like McDonalds - where you order the food with someone and then pick it up from someone else) are also pretty foolproof.
However, at food courts you could "accidently" use a CS when you meant to use a snack credit. So those are the places you would have to watch out for. The menues and CM's will help here, but it all comes down to the CM at the register, as to what they count as a snack or a CS.
For instance, at the Sassagoula Food Court, we got two CS and two snack credits - which we verified with the CM at the window - however, when we got to the cash register, the CM claimed we had 4 CS! So I had to stand at the waste basket (conveniently located at the cash register) and throw away the "extra" food items (2 slices of toast and 1/2 an oatmeal) to be down-graded to 2CS and 2snacks. Out of control CM? Maybe.

What a waste of food! You would have thought that if one CM said it, the other CM would have allowed it, but NO!

she insisted I throw the food out.
