What fake name do you use at restaurants?

[Megalyth]

Not a restaurant, but there's a religious compound of sorts on my delivery route that requires a sign-in at the gate. I've used Franz Ferdinand, Snidely Whiplash, Yul Brynner, William Blazkowicz, and a bunch of others. Any odd name that I think of on the spot will do.

I told my Krispy Kreme store I was 420GlazeIt, but their donuts tasted the same as ever...

They always call me SirIhave Toaskyoutoleave

People actually use fake names at places?
