Clerks at the Wallmart Counter

Is it just me or dose this happen to everyone? I went to wallmart and bought some Halloween stuff and the clerk says "Getting ready for Halloween?" I know maybe they are supposed to say something but I don't like them commenting on what I buy I think its rude. Like, what if I buy condoms cavateea and berry white music would they ask if I was getting laid? Just my thoughts for tonight.
love,
