getting on my nerves

My schedule's JAM PACK TILL THE DAY I TAKE LEAVE which is like 25th OCT
like 9am-6pm? or longer, and I can only manage sneaks back to the office.

STOP ASKING ME IF I WORK AT NIGHT. I DO NOT.

I USED TO DO IT OUT OF GOODWILL.

NOW I must be selfish for my own sake. DO NOT take my goodwill for granted.

and one user brought his prof to NEGOTIATE cause my schedule's heavily booked.. its not my problem alright?

then say his lab (somewhere else) not ready yet or else he wont use it here etc etc.. fine, i am not your first choice, it doesnt matter to me.

then explain he will buy his own and use his own ppl .. so what's that got to do with me?

then asked if i can squeeze in his student..
he ask why i cannot do later in the evening..

what I do OUTSIDE of office hrs is MY RIGHT.

I step into the lab first before going office ..shucks.. maybe I am too "pampered" regarding my office hours but I cant afford the do do OT NOW.
