I think they don't seriously cheat about not refilling gasoline, but the quality of gasoline is always different, sometimes they bring a good one, and sometimes diluted. Two months ago I changed the gas pump, the other day it stopped working, and when the master disassembled it, they found a lot of dirt and traces of water in it. By the way, I've been refueling with them for 2-3 months now, I could refuel once in their other branch and twice in a Russian mustang.
