We also thought this was a mistake, and pointed it out to the front desk at our hotel after the meal - the CM was less than friendly about it, and stated that the TS charge was correct because we had asked for a plate for our son (he didn't even get a drink, we had juice with us!!!). Needless to say, we were NOT happy about this, but what else could we do? Thankfully we did not have this experience at any other restaurant. I am glad to hear that no one else is experiencing this - what a waste of a TS credit! But we weren't going to let one bad experience ruin the rest of our otherwise magical trip!
