I know this thread is meant to sneer at excessive 1 token tips, and for the most part I agree that it is annoying, but for many models that linger in the back pages of CB I think they make a difference.
This evening I waited for a purple user spending his 200+ tokens in 1 token tips on a model I had arranged to take for a private, I should say that it was my decision to wait.
The model had been online 2.5 hours when I entered, had 3 grey users in the room, no chat at all, and a goal that read 0/88. So I thought: I am not in a hurry, let him spend some tokens on her. I told her I was waiting for him to finish tipping, I got a giggle and a wink, and when he reached 200 tokens I got a message: 'I am ready for you now.'
Of course I would have kicked myself if he had decided to take her for a long private, but I could see that he was not communicating with her, neither in chat or PM, so it was a calculated risk.
