where everybody knows your name, and they're always glad you came (?)

Tonight at the hospital the man wrote down my name on the receipt after I had ordered and I didn't tell it to him. Then later when I walked up to get more barbecue sauce he said, "Yes, Dallin?" I don't know why he knows my name. I don't even remember anyone say my name before we ordered or anything. Weird. There was also this lady who cursed under her breath when she saw us walk in. Just like Cheers.
