I use different 7-11s. & family a lot when I'm there and can honestly say no one has ever tried to rip me off.
One outlet that have tried to scam me on many occasions is the petrol station on Prabaramee rd.
What they do is fail to return the pump to zero from the previous customer.
You ask for say 60 bht worth, the guy puts 40 in and charges you 60.
I've seen them do it on many occasions to falang.
These young guys must make a good living from this scam.
I always make a point of watching the pump display. even then sometimes the attendant will try and shortchange me. If this happens I don't say anything, just keep my hand out and they always put the rest of the change in my hand.
I think if you act like a first timer, you are more likely to be scammed.
