it's my life

When the office printer’s type began to grow faint, the office manager called a local
repair shop where a friendly man said, “The printer probably only needs to be cleaned.
Our store charges £30 for a call out to do the cleaning. So you might like to try reading
the printer’s manual first and doing the job yourself.”
Pleasantly surprised by the repairman’s candour the office manager asked,
“Does your boss know that you discourage business?”
"O sure.” Says the repairman. “It was his idea! We usually make more money on repairs if
we let people try to fix things themselves first.”
