@vince9 How much did they pay for these shops? The only STN tobacco shops I have come across were those pricing audits. It could be that they don't show up for me since I am above that age range.
When you did them, what was the process? Did you have to get a manager's signature? How long did the stop take on average? Was there a cap in how many you could do in a certain period of time like the post office shops where they want you to wait 30 minutes in between stops and they don't want you to do more than 5 in a day.
I came across a post a long time ago where the OP said he was paid $30 per for these age check stops and they were giddy about doing 8 of them in a short time span. Something like finishing them all in the morning.
Someone told me that they have age compliance shops, not STN, in their area that never appear to be taken by anyone.
