Shoprite Woowee!

So today I was at shoprite and I was getting some pasta because it was on sale. I was standing at a huge display at the end of an aisle and this old ady walks up to me and goes is Pam down this aisle? My first thought was to look at her with a straight face and say "I don't know Pam what's she look like?" but then realized how dumb that was and just said I don't know. The lady kept asking me for help throughout the store. Do I look like I work at Shoprite? I was wearing a green shirt their employees wear grey sweatshirts! Did this woman think I was her personal helper. Whats the deal with old woman thinking everyone is there for their service it really pisses me off.
