I had the same experience a week ago at a walgreens down the street from my house. My fiancée and I have shopped at walgreens for 6 years, myself much longer.
Out of the blue, while shopping for wine and some late night snacks, the cashier asks for both of our ID's. She had to go into the parking lot and into the car to get her ID so we could buy the wine. Same store same cashier.
I go to CVS now. The cashiers attitude about the whole thing left me madder than *** It's not Louisiana law, but apparently it's a new walgreens policy.
