People who go to a restaurant in a 2 hour wait, why even bother putting your name in for a table?

So i work at a waterside seafood restaurant in a beach town so summer is our money season. Yesterday was the first semi cool (85°) day after a heatwave and it was slammed. I was working the bar meant for people waiting on a table and it was a zoo. Even after being informed of the wait people were bitching at me the entire time about how ridiculous it was that they have to wait to eat. Like just go somewhere else.
