So Uncle Bob was supposed kill every single person in that bar to cover for him stealing some guys clothes?
he shouldn't even be there from the beginning. why does a terminator look for clothes? to blend in. so he has a concept of people reacting bad to naked people. then what the hell did he do there, in a crowd of people reacting bad to naked people? that's an enormous logic hole in the script.
of course if he just killed everyone, it will be almost ok. almost - because i guess 1994 already had security cameras which he had to spot and never enter that bar at all. and actually that movie had to take a completely different direction right from the beginning, as all morning news and wallpapers tell a story about a naked man of enormous strength, immune to any damages and having no feelings.
that bar entrance was as stupid as it only could be from the point of logic, like it was T3 and not T2.
well i see you just wrote the same scenario from another point of view - from inside the movie and not outside.
still it's stupid for a terminator to enter a place full of people (he should have understood that by the number of cars and bikes outside) just to get a way of hiding from those people.
to attract attention to avoid attention. it even sounds stupid.

on another hand... reprogramming a terminator VERBALLY was what resistance had to do, and it was their first attempt. no wonder they made him a little retarded
now T1 speaking freely and T2 making dumb statements sounds even logical.
=================
jokes aside, i have two variants for T2's "kindness" in the beginning.
a) no matter what intentions T2 entered that bar with, he should have quickly changed his plans, seeing how freely people sit there, laughing at him, and (supposedly) how hidden cameras monitor him. and that's where a-dev's scenario is executed. in a bit too aggressive way, but the cyborg couldn't come up with any softer plan including "pleeeease" words.
b) i wonder how smart/dumb a terminator is when he awakens. it's a learning artificial intelligence, right, but in what state does it sleep in rows in skynet's undergrounds? what does it already know? it should at least already know how to control the body, so it had to take simulation lessons while remaining bodyless - but what does it actually think? i wouldn't wonder if both terminators, being just woken up, don't know, think, understand much yet. they are like being born into real world from simulated sleep.
and T2, unlike T1, should already have spent some time among humans in future (they had to check him, program him, tell him some stories, walk him to the TDE and so on). what if he didn't expect hostility from big numbers of humans, as first humans he saw were in numbers and didn't attack him?
