Beg him not to call cops

"Please don't", you finally manage to say something, "I didn't realize that it'd be this bad."

You watch the wide smirk on the clerks face. He knows that he has you now.

"Hmm, maybe we can figure out something else...", the clerk says, pretending to be thinking hard, "Maybe you could come up with something that makes me forget this little mishap..."

The clerk makes a meaningfull look down towards his crotch. You don't find him attractive at all: He's overweight, sweaty and his age is probably near to 50. But what other options do you have?
