<human>: Give me a shortened version of the text

Ok I wear invisalign for my retainers after drinking some coffee I leave them on some napkins. Flashforward I walk into the bathroom. Walk out the coffee and napkin beside it is gone and I'm freaking out because I thought someone threw away my  napkin with the retainers in it. I ask management and then spent 2 hours looking in the garbage for them because dental insurance is expensive af. Alas no luck and I smell like trash. While driving back home pissed af, I open up my backpack and see my fucking invisalign in it. With a note saying "I put these in your bag for you" - stranger. MOTHER fucker.
<bot>: some nice guy put my retainers In my bag and left. Made me hyperventilate and dig through garbage for 2 hours.
