I'm embarrassed to admit that we've left quite a few restaurants with totally filthy floors prior to discovering this product. We were the couple that would have to leave a double tip because our son decided to leave 2/3rds of his meal on the floor underneath his high chair. Ever since I got these, I've been acknowledged by every restaurant's wait staff about how awesome and considerate we are. We place it underneath the chair, and it captures most of the stuff that's inevitably dropped. I do wish they were round vs rectangular to capture more around the chair, but I'm pretty happy overall. They are a bit pricey, but I figure the savings in tip money is worth it!
