This just happened today to me: I stopped at Baskin Robbins to surprise my family with a little treat. The girl behind the counter was morbidly obese. Sounds about just the height and weight of the woman in this story. I have to say that all kinds of things went through my mind. First of all, she could hardly reach over and get the ice cream from the buckets. It took her a longer time to make the order and, I have to admit, that I just got a single scoop for myelf because, frankly, after seeing her I questioned if I should really be eating ice cream in the first place.
That being said, of course she should have the right to work there, but there are negatives for the business.
