I was being harrassed by a group of customers, ended up crying, and walked out of my shift early. I guess I'm not stable enough to handle customer service, and that was my bad for accepting the job. My supervisor hugged me and told me it was okay, but I saw a job ad for my position posted online. This is for a small business and I'm the only person in this position so there's a 90% chance I'm just being fired.
Should I tell my boss I saw the ad (he would know I was looking at jobs though) and ask about it or just wait to be fired so I can get unemployment?
