CO2 tank visual inspection - Rip off?

[christyf5]

Weird. I pay anywhere between $18 and $22 for a fill and I have never had to pay for a "visual inspection" in the 5 years I've had my tank. I just had to have the hydro test done last week and that was only $15 (which I was shocked at, I thought it would be closer to $50). My CO2 guy does give it a hard look every time I take the tank in as its sort of rusty on the bottom and generally ain't pretty (I think its about 50 years old) but it passed the test and got the stamp and thats good enough for me until I can find another one.
