Just had a lady from come in and say "This shop is called Shaftesbury Wines, so are all the wines from Shaftesbury or are they foreign 'cos I don't like foreign wine" FFS! The last person to ask me that same question was visiting from Africa so could be forgiven. This one was from Birmingham.
Best/worst was a chap who pulled an aquatic pump from his bag and asked if I had a small guage pipe that might fit it. I asked why he thought a wine shop might sell aquatic hose and had he tried the pet shop. He said the pet shop had suggested me. Why? "Well, you probably use clear plastic piping when you make the wine." Not taking "Fuck off" for an answer he spent 10 minutes looking around the shop in case I has a roll of pipe secreted among the Burgundy.
So which of you has made a tit of yourself in a shop?
