This particular clerk needs to get a bigger gun...
AND load up with hollowpoints. :) Cor-bon, Hydra-Shok,Gold Dot or even the garden variety Winchester brand sold at your local Wal-Mart.
I guess you can say the clerk was providing that extra special personal customer service that is so lacking among retail staff these days. It may be that the slogan for the company was: Greet them with outstretched arms...the kind that shoot bullets.
