My wife went to the deli to purchase potato salad and other things. When returning home, we found the cheap! container lids had popped open. The containers you're currently using are very flimsy. In fact, they are Garbage! We don't like serving food out of shopping bags. These are the little details that don't warrant customer loyalty. There are just somethings you can't go cheap on.
Desired outcome: Change your containers to a sturdier type for your deli department.
