I was just thinking, in restaurants where an average meal costs $50, and they have multi-thousand dollar bottles of wine, do waiters and waitresses actually get 15%-20% tips on the costs of all those meals? If someone buys a $10,000 bottle of wine, do they get a $1500 tip? And what about in general, even among people not buying wine, where the average person spends $100 total throughout the evening. Servers would make hundreds an hour if they collected an average of 15% tip on everything. Is that what's happening? Or is there a different system for such places?
