Have you ever been fired?

Many, many times.  Laid off, too.  Quit a lot of times, also.  Being fired is not always your fault.  Sometimes the business has problems.  The IRS closed one business I worked at. 

Sometimes your supervisor is making a scapegoat of you to cover their own mistakes (happened doing quality control, the company went out of business the year after they fired me by losing all their contracts for poor quality).

And sometimes you screw up and deserved to be fired.  As I like to say, make many mistakes, and have few regrets.  We learn from our mistakes and you probably won't have the same problem at the next job.

Or was a simple 'yes' the answer you wanted and the rest is just rambling? 

No actually all jobs i took , I found myself quitting. I guess its a type of person you are, maybe sometimes you realize before your bosses that this job is not for you.

Once I was fired from a crummy summer job serving pizza at a pool snack bar. lol

Yeah        realy had to work hard in order to get fired but after several months of persistant random tardiness and questionable performance I was able to coax out the "we are going to have to let you go"out of a less than desireable employer. I was pretty proud of him for facing that responsibility in his company I think I was his first.
