that fucking sucks. Sorry to hear that man, don't give up though. ?

Do you have the contact information of your temporary boss? If so call him and ask what you should do, or see if you can reschedule.

The way this is written I imagine a stranded kitten sitting outside a store in the rain crying to be let in because it's been forgotten outside.

Is it possible the sign is from 2 weeks ago and they're about to come back?

Try to contact someone, and if you cannot, leave a note/show up after the two weeks! Make sure to take a picture of the note they put up so you have proof. (Especially if this is for a college course requirement!!)

Who has a two week internship lmao

In Germany, 9th grade students have to do a 2-week-internship as a part of school to prepare for the "adult world".

Are you sure it wasn't a prank? It's very coincidental.

Was the notice dated?

Sign of a great company to work for, only a sample of what is to come. that suck so you go work for the competition shit on them every chance you get.
