I get what you are saying here. And it’s possible that some people are jumping to the wrong conclusion, however each person is different. Some people will think nothing of it like yourself and others (like me will find the op’s behaviour borderline obsessive)
I have no trouble working in a customer facing role. I’m friendly, chatty and can get along with most people. However, to me work is work and if I was to see my clients outside of my work bubble, let’s say on the street I would probably be polite enough but that’s as far as it would go.
If these clients then continued to badger me about booking them in along with gifting me expensive gifts, I would go out of my way to avoid them as I would feel awkward and slightly smothered and like they were trying to force a friendship on me that I didn’t want.
They aren’t my friends and are in some ways a still a stranger to me. For these ‘strangers’ to then keep in touch with me outside of work and push gifts on me (expensive ones like £100 in a card), I’d think they were the batshit ones.
A box of chocolates at Xmas as a thank you, fine. But a box of chocolates and £100 in a card? That’s too much, especially for birthdays and Christmas and I’d find it odd for a client to go to this level of effort. First of all I’d feel like I’d feel like I have to return the favour when it’s their birthday or Xmas when they aren’t even a friend or a relative, which is a road I absolutely would not want to go down. Secondly, I just feel it’s highly inappropriate. If the op was a man, gifting me all these things at Xmas and on my birthday, I’d start to think they had intentions other than just being ‘a friendly customer’.
The fact that op seems invested enough in this woman to create a thread about her, on top of the gifts she’s been buying her and on top of chasing her for an appointment, indicates to me that the op doesn’t appear to recognise healthy boundaries.
So whilst the poor woman that is at the centre of this thread may or may not be just fully booked until September and may have forgotten to tell op when she was available to book her in, possibly did not intend to come across as avoiding the op, I do find it strange just how far op has taken this (non friendship) by buying personal gifts for her Xmas and her birthday, chase her for a booking rather than just finding another nail technician who could fit her in sooner and then feeling the need to write a thread about her. I don’t understand when, if op really wanted/ needed her nails done, why she would wait around all this time without going to a different nail technician. It seems a bit bizarre if you ask me. Even if op’s doesn’t intend to come across as obsessive or suffocating, I know I absolutely would take it as her being like this and would not want to deal with her anymore.
