1) why was he supposed to suggest a time window? you asked for times and he gave you specific ones, and then you were the one that suggested 10pm not even giving a fucking time range yourself if you are trying to say its mandatory in any way.
2) he suggested one time for today and then when you said you couldnt make that time he agreed to the time that you suggested, was he supposed to reply to you again with more times after that or what.
3) he gave you adequate heads up as you were already 40 minutes late and he had to leave, we tagged osh as well in the managers channel so he would be aware as well and could maybe get a sub if needed. once again, you were the one that was 40 minutes late so its not on him at all.
also to recap, star at first requested thursday/friday at first, and once it was clear that wasnt going to work out he made time on saturday. from the start you have been the one with terrible scheduling, not offering times at the start, just a simple "gmt+1 when fight for nupl". not figuring out times till the day of the scheduling or the day before, and waiting from monday->thursday to even reply back to him. this should be a fairly clear cut activity win, you missed the time by an hour, star said he wouldnt be able to do sunday, and this was the result.
also re bughouses post, he played that game on his phone for a tour on a random other subforum because he was at risk of losing off of activity there. in this scenario he has no reason to handicap himself by playing on phone for this tour because teddeh, not him, was the one that missed the scheduled time by over an hour.
