getting rehired after being fired from a job

I have to say that i can not believe that i can get a job.I have been on about 6 interviews,and noone will give me a chance after being fired from the comfort inn on delaware ave.I dont know what people thing, oh she stole something or something no, this was not the case at all. Turns out i was fired for nothing because what happened was a manager had givin keys to a dirty room to a guest,i got the blame even though i was not on site. They also wanted to hire people who would work for less money. I have been in customer service for over 10 years. and i know not to give a guest keys to a dirty room.Its crazy i have resumes on allmost every website i could think of.if only i could get a chance to show my skills and dedication to my job. but no comfort inn is saying something to keep me from working, its not fair
