You Never Know What's Going to Come Through the Door

Everybody needs new clothes sooner or later, even the creatures of the night. But pity the poor sales clerk who has a vampire for a customer. No matter, in retail, you never know what's going to come through the door: maybe a shoplifter or an undead teenager who wants to buy the same sports coat he wore in 1959. If it is the latter, you're still going to be expected to greet him with a smile and make the sale. Even if it costs you your life.
