We have the same over here , I could not shift a box of stuff I had picked up . So stuck it at what I purchased it for, in come Mr pain in the ass I will give you hell and speak 1/2 English . I told him speak bloody English and watched his face he thought he was going to win . So I turned up the heat started to speak very loud in Geordie then broke out my temper with a few expletives and went for his money . Odd how quick as a flash he shot the cash on the counter, did not want any of his own medicine . I grinned as I took his cash off him .
