My girlfriend left her car/house/work keys at a local bar, last night. The owner (after she called him) said that he "if he feels like it, he'll go and look for the keys." What would you do?

Her new coat has big pockets and she is %99.9 sure that they fell out when we were snuggling on the couch there. The bar is only open on Friday and Saturday nights. The owner lives 30 minutes away. He was rather rude to my g/f over the phone.

She needs to get back home (to the U.S. We’re in Canada right now). My vehicle is in the States getting fixed.

Anything that we could say to him, so, that we could increase our chances of him following through for us?
