I'm sure you're right, because that's the general attitude they operate with in that industry, but I was a server for six years and most of my friends still are, and it's totally unheard of for a server to end the night below minimum wage. I've never known a server to come away with less than kitchen staff and the norm was much higher. A really bad night at a cheap buffet was 60 in five hours. If it was slower than that servers and kitchen staff would just be sent home.
