A few years back I bought some swimming shorts on the Sunday market. later that week I went swimming in the sea with them. The metal eyelets instantly went rusty. Took them back the following Sunday for my money back. "No" was the reply, "you have been swimming in them" (
) After a few words were exchanged he still refused, so I told him I was going to find the market supervisor and tell him what was going on. Instant change of heart and money refunded!
