It Is Sooooo easy to do. In fact it's pretty great. Get a coffee, a donut or whatever, sit in the parking lot for a half hour, hour and just wait for people to come out. Then ya jump out and ask them if they want a mag and yer done with that.
Although.... one time this woman came out, one of us offered her the mags, then she promptly went right back in and complained to the management and they came out and told us to leave.
In hindsight.... good for her!
