Assuming this is black iron pipe being fastened to the exterior wall, I would expect about 1-2 hours in end connection work depending on how easy this was to tap into the gasline near the meter plus about 25-30 LF/hour putting in the pipe itself - assuming straight run like you said so using 10' lengths. With 1" pipe I would expect two plumbers on the job. So depending on how long your run was I would have expected it to take at least 2 and commonly 3-4 hours for two guys - that is 4-8 labor manhours.

Certainly if this is a high-pressure run (tapping off the incoming gas line BEFORE the meter, running high-pressure to the generator, then another pressure regulator or meter (depending on your meter design - some measure flow in high-pressure gas, mosat on the low pressure side) there, which would most likely have been needed if this is a whole-house capacity backup generator, because the low-pressure household side of the meter usually cannot provide enough gas for say a 5-10KW generator to run on.

May even have required changing out the existing meter to a higher capacity one.

So - bottom line - if just tapping easily off household low pressure line to a small (maybe 1-3 KW) generator, sounds high to me but not seeing all that was involved ... If for a basically whole-house capacity generator then yes, that is basically a man-day of work commonly - that installation commonly runs in the $1000-1500 range all told.

If you have a concern on their billing, presuming you were not home to know how long they were actually working on the job, call and ask for an explanation of what they did that took a lot more time than just running some 1" pipe.
