I said, "Excuse me, I've been waiting in this line." He gave me a foul
look and said, "Too bad, you gotta keep moving", and the cashier began
scanning his stuff. He was about the size of a Sumo wrestler and
speaking with an slurred eastern european accent like he was half in the
bag already.

I had a somewhat similar encounter at Home Depot.
Same accent, same size, long line. He was arguing
about being overcharged $.12, wouldn't stop, wouldn't
leave, I pulled a quarter out of my pocket and gave
it to him and he got all upset at me...
