Why would i tell porkies? Why do you find this hard to believe, is it coz you only got to Makro and Lotus once a week and that's the only time you're out, oh and maybe for a couple of Changs?
A better way to look at it is about 1 ticket per 1000kms ( ish )
Some of my trips i accumulate 5+ per day, have you been out of Pattaya lately trans, there's cameras everywhere now, it really doesn't take long to rack up a few. Bear in mind there's probably a few that don't work as well.
