I'm very shy and don't want to be friends with the people behind the drive-thru speaker. They always ask for my name. I don't really like that. It's not a huge deal, but I don't want my name announced out there: Hey Scott! your greasy fast food fried chickens' here!
I tell them "Elvis". And everyone totally loses it. they tell me they don't believe me and act like A. it's the funniest damn thing they've ever heard and want to chat me up and joke about it, or B. it's totally scandalous and want to spit in something. Not an isolated incident. What if that were my real name? I know of at least 3 Elvises: Presley, Costello, and one of the chicken hawks from Looney Tunes, so it's not inconceivable.
Sandwiches are good and cheap. The bag that the sandwich comes in is more air-tight than most and if you don't open that up and eat quickly, your bun can get steamed soggy. So don't get it to drive home and eat 20 mins later.
