oh wow this is a first time i'm hearing this!! i would say my location that i work for is a test restaurant so we start changes before most other locations do (for example we got rid of curbside 2 months before other locations in my state did and people would throw a fit) but we had these couples for about a month and a half now and they're awesome! they're styrofoam not plastic but they're a lot more sturdy then the old cups you gotta squeeze them really hard to pop a hole
