I have received cash after purchasing fuel, not sure how much they charge to cash a check w/o fuel purchase.
Usually if u don't fuel they charge a percentage but u call to find out
Have not tried it but in my experience any t/c that takes comchecks can cash them but there are either a limit involved on how much and also fees up to $8.00 unless y fuel a certain amount of fuel usually 100 or more gallons.
Most likely I would call them and ask first
