Also, if you work at a grocery store, and I am paying with a credit card, do not pause to scrutinize the receipt for several seconds before handing it to me with a perky "thank you, Miss Brumble!" Nobody calls me that. If you actually knew me at all, you would call me by my first name, like the pharmacist in the back (Wayne) does. Do not pretend familiarity. Just give my my receipt and my goldfish crackers and leave me be.
*Furthermore, do not point out items in the store and gush about how great they would look on me. I am a timid clothing shopper, and you will scare me off to a store where I can browse quietly. Also, I am not fooled, and I know you work on commission. Go away. I will ask for your help when I need it.
