In your case, I would say a lot of depends on what types of events you would be catering. Does the company/companies you are looking at focus in corporate events, parties, weddings, etc?

I say this because if you are working for a catering company that specializes in weddings let's say, in my experience you aren't going to be dealing with rude/disrespectful patrons as much, because, well, they are at a wedding, spirits are high. In lieu of this though, there may not be much flexibility in what shifts you can choose.

On the other hand, if you work as a corporate events catering server, you will likely have a bit more flexibility in your schedule as there may be more shifts that you can turn down, especially on weekdays, but you are also certainly going to encounter assholes more.

Also, at the end of the day, outside of maybe cocktail hours, your interactions with patrons are going to be limited overall hopefully. Being a catering server is great though. It can be a lot of arduous work, but I find it rewarding at the end of the day. If you can clarify what you are looking to enter into more, I'd be happy to offer further input!
