I was taken there about 12 years ago by a business associate who had a shop there for a look around, one day/night and return...
I never returned either
I often speak with staff at my local 7-11 and on my weekly trip to Big C to stock up, none of them say they are being exploited, rather they are happy to have employment.
As are the other mini-shops within or outside of these establishments
Not sure they have the "right" in law... they may under emergency conditions using extreme caution cross through a red light.
However they are not absolved from responsibility if causing an accident while doing so.
