Standing in the shopping cart
I see this all the time and today I saw a toddler go tumbling out of the cart, head first. In the past I have commented to parents that they shouldn't let their baby stand in the cart, but I mostly get nasty looks. So, please if you have a toddler, don't let them stand in the shopping cart. It is very dangerous and people who comment to you are trying to keep your child from being hurt. It is careless behavior, IMO.
