Check receipt before walking away
Twice in the span of 48 hours I’ve had an automatic fuel-service charge applied to my properly filled rental. One of them was an “under 75 miles flat fee,” and the other was simply labeled “fuel service.”
The agent was able to fix it… but right now the extra scrutiny is worthwhile. I hate taking the time at the counter to review the charges, but I’m not sure I’m aa trusting of the travel industry as I once was.
