Went to Glen Uniqlo to change a bra which I bought was too big.we old people are very forgetful, so I used a tailor pin to pin the receipt to the bra. the counter girl saw the pin, immediately she disappear, came back few minutes later and said the can't change it, because I put a pin there and they can't sell it again. Such a big company haggling over a tiny little pin .waste my time waste your time don't you think is stupid doing business like that.
