How 'bout ... you take your car to the shop for the 9am appointment. Right on time.
Mechanic drives it to the lift, and raises it up.
Mechanic immediately gets called to the front desk. Another customer wants to "talk" to him about possible mods to his car - which isn't even at the shop. Customer won't shut up.
After 90 minutes (yep, 90 minutes), mechanic is still stuck with customer who won't stop yakking.
I walk up to mechanic, and calmly say "So how's the work on my car going?"
Mechanic says "It's really busy today - sorry." Yakking customer then realizes what's happening, and leaves.
Mechanic starts to work on my car.
Good grief.
