Was it iHop? Because I worked there too. Worst fucking job ever. And yes I remember doing a switch from glass bottles to plastic, probably because of YOU
My favorite thing to do at iHop was throw everything away. Just everything. Plates, dishes, cups, highchairs, ramekins, full ketchups. One time I threw an entire box of about 36 full, brand new A1's into the dumpster. Why? because FUCK THAT PLACE.
My favorite thing to hear was "Guys make sure you give your customer plastic togo containers because they have been taking our sauce dishes home in their boxes."
That's when I say "Yup I see it all the time."
