SELF HELP

I was grocery shopping today & wanted to BUY something that was NOT ON THE SHELF!
However, there was a CART with boxes stacked on it, with SEVERAL SEALED BOXES of what I wanted. NO employee was in the aisle for me to ASK to OPEN A BOX, so.....I did it MYSELF! LOL I took 2 packs out of it, put them in my cart, & walked away! Naturally, I PAID for them at checkout, so...... I don't see a problem!
Years ago, I may not have been so BOLD; BUT.....WHY should I LEAVE the store WITHOUT the item I wanted....when I could just HELP MYSELF?
