Be alert at gas stations
Recently went to the Pemex gas station on the west end of Centro to top off 2 ATVs. I watched the attendant fill up the first ATV and the total was less than 60 pesos, then he filled the 2nd ATV and the total came up to 98 pesos.
I turned away for a split second and in that time the attendant pressed a couple buttons and when I turned back I saw him manually enter a new total of 299 pesos. The screen no longer showed how many liters were used. He told us this is the total we needed to pay.
Fortunately my wife and I speak Spanish fluently. We told him that we saw him change the price and to show us what he actually put in. After a bit of back and forth he pressed a few buttons and our original total cost and liters appeared again. 98 pesos.
We paid the correct total and were on our way. Please make sure you pay attention and don’t get scammed.
