Since I am a wheelchair user is it unreasonable expect assistance in the supermarket because stock is either too high or low for me to reach. Last time I went to the customer service counter and asked I was told no one was available right then.
I waited ages then gave up and had a go. Trying to get a milk bottle down it fell and split splashing milk everywhere. People popped up all over and trotted over asking if I needed help. It's awfully tempting to go in next time and drop something messy.
