wow, I am new to this site, shocked at all the replies. for starters, our magic bands which you can put charges on your room are attached to my credit card. for the comments about waiting to the server to return, that would add significant time to leaving, generally the servers are very busy and they don't always return in a timely fashion. We did this practice in all our sit down meals, only 2 servers charged my credit card , they other servers had the common sense to figure out what was their tip. My daughter was a server through high school and college, she agrees that this is common knowledge when money is left, after the money owed is paid the rest is the tip. Furthermore if the bill was 60.00 would you leave a 30.00 tip? that would be a tip of 50%, I doubt anyone of you leave a 50% tip. BTW... if your reservation is held with a credit card yes they can charge to that card for a no show or late cancellation.
