A good few years back a colleague said to a customer "can't be long now eh?" nearly in tears(crying not laughing) she responded "I had my little boy 3 weeks ago" [/quote]i have also done this , but only once !
Another embarrassing moment.... Canvassing a while ago and this young lad came to the door, I said, "Is Mum or Dad in?" and he replied "THIS IS MY HOUSE!"
