Circle K

I went to this circle as I usually do for gas and I go in the store and pre pay. Well I did so as usual but the machine said total 70 dollars and not pre authorize. Me thinking that maybe the company changed there system or something as a lot of company's like to update. I put in 55.75 of regular gas between 7:20 PM and 7:30 PM on Jan 16, 2020. I check my bank later on that night and it says I was charged 70 dollars meaning that the guy at the desk doesn't have a clue how to pre authorize or just felt like screwing me out of my money. You can bet that I'll be letting other people know. God only knows how many other people this is happening to
