Guys,
At the end of the day what is termed as a crawl, to one person may be moving fairly quickly to another. Those in shops, deal with people of all persuasions, and again the above is true for them. There is no guarantee when the loco is returned that the same person is going to be handling the return item either, ALTHOUGH if that were the case one would hope that the message was communicated to the OP!
