['I had a repairman out to my house yesterday to fix my a/c.', 'Let me guess, they are trying to overcharge you?', 'He fixed the problem lickety-split and did not charge me a dime!']
Wow!  That is a welcome surprise!
I wasn't sure how much or how long it would take to fix my a/c.  It took the technician 15 minutes to fix it.
