Stop and Shop Supermarket

This market is very good. It is spacious, well lighted and, for the most part, is never too crowded. The shelves are well stocked.
Yesterday though we bought a package of hamburger rolls that clearly been nibbled on by a rodent. (The plastic had been chewed and part of one of the rolls had been eaten.)
My wife returned to the market today to return and replace the rolls. When she returned to the shelf where the original rolls were sold, she found a few other packages of the same rolls with similar areas of chewed plastic.
She then went to the customer service desk to report the problem. The store assistant manager she spoke to was, in her view, surprisingly unconcerned and unhelpful. In fact, he tried to tell her the hot rolls sometimes melted the packaging that way. My wife pointed out the the rolls themselves also had been clearly nibbled but that comment was apparently ignored.
Yes, she was given another package of «uncompromised» rolls, but she was taken aback by the manager’s casual dismissal of the problem.
