Trippy, we all have days like that, it's not about quiting smoking really. If you have, lets say 300 custies, and you get a day like today, it could bother anyone. If you had 600 custies how would you see it then?
Honestly mate, who cares what they say? If they get funny with you, replace them with two new ones.
It's like being on this forum, some agree with the shyte we type, some don't, who cares? Make these type of custies unimportant. It doesn't really matter does it?
Chin up and get the money they owe you.
