I recently had a Coke at work and was really distracted (super busy), and it had been setting there for several minutes without being moved. I then took a drink of it and felt something odd when my teeth came together - almost like wadded up thread or something. It was a fly....
I did my best to keep thinking about the thread, but it didn't work too well.
From now on the top goes back on the Coke
every time I put it down.
Now you don't really think he would have agreed it was a spider, do you?

OP, talk to the manager or even the corporate office, but the FDA won't particularly care. It doesn't really fall under the umbrella of responsibilities.
