We never did it with the kids and it was usually 4 little ones, until I was deemed old enough to stay home with them while the grocery shopping was done. We would either take something with us, or buy something before we went into the shop, I usually had 2 kids in my trolley and there were 2 in the other trolley, and by the end of the shop both trolleys were usually chockers (there were 7 of us), and one of the little ones riding on the outside, the other in the seat.

With my own, would I do it, no, I find it morally wrong, I won't even open a drink before I've paid for it.
