Whats the easiest way to piss off a customer?

[Yard Bird]

Above all the ways you can think, what always pisses off every customer, every time. Here are a few I can think of that do work.
1. Arrive 2 hours late
2. arrive with a 8" slump when it call for a 4"
3. washout outside the designated area
4. Arrive with a broken discharge cable
5. Forget your water valve is open when you pressurize your tank
6. Get lost
7. Arrive with your hose dragging, with nothing left but frayed rubber.
8. Hit the pump truck
9. run out of fuel
10. Run over their transit
11. Never get out of the truck
12. When a customer whistles to pull up. (stop and get out), tell him your not a dog.
13. Become a mind reader and never get it right
14. Back through a patio door while the customer is guiding you.
15. Tell the customer you can't fit the truck where he wants it
16. pull up to far and back up to little.
17. run over the crews tools
18. Live long enough to put this list together

Once you really get to know all your finishers you learn who hates who. For instance, let's say Jim hates Bill.

As you watch Jim troweling the edges, whistle and say, "Man! That's good work! I mean it ain't "Bill" good but you could sure be one of his trainees".

A guy at work hit a sanican. It was probably an accident. The second time he hit it was probably an accident too. And the third time. The pump operator that was inside? He had less of a sense of humor about the whole thing.

I found out that they don't really care for me running over their edgers, either. Especially when the set it down right where they want me to back up. I wonder if they were madder about their own ignorance or my destruction of their tool.

Then when they order an OshKosh because of the extra chute, spend all day trying to rent a chute extension at a rental place, and I won't let them hang it.
