They can only abuse you as long as you let em. Then they'll find someone else to abuse and take advantage of. It's just their style and it seems there's more and more of them all the time.
I've been there. Just cause they ask, doesn't mean you have to say yes. Heck I got a feeling some people think they'll never hear the word no. They get what they ask for like magic.
I have 2 customers that have ordered their 2nd cord and it’s not cold yet. I would be comfortable having these 2 and 1 other as my only customers. All 3 will buy 3-4 cords from me before Feb. I might keep the only fans customer on my vip list too. They are less than .25 mile from me
