"How can money be the root of all evil, when shopping is the cure for all sadness..." Elizabeth Taylor
You're incredibly busy and someone asks to have a product gift-wrapped.
"Sorry, I can't do that today. We're too busy".
"You'll have to wait until I've finished serving these other customers".
"Not today. Sorry".
Or, the wrapping is poorly done with an equally poor attitude. Mind you, I've also seen perfectionists take an extraordinarily long time wrapping a gift whilst other customers 'silently fume'...
