I am over it and will not post anymore bad comment on taren64 after this post.
Just clarify a few points:
1. The message from papasan was sent 10 minutes after I booked so it wasn’t immediate. But it wouldn’t make any diff as I was driving.
2. If he was apologetic and was trying to offer me a discount next time last night, I wouldn’t be that mad. But his attitude wasn’t like this last night.
3. I have tried to extend in other shop but if the girl has booking, then the keeper would not let me extend and i would understand because there is a booking to honour.

Apology accepted but will not go back even I am offered a free session.
