The "tit grab" gave us (the audience) a reason that Uhura didn't like (or respect) Kirk for 99% of the movie. . .
But it's just redundant, as the lame pick-up attempt served the same purpose. Plus, how shallow is Uhura that she would hold something like that against him because it was clearly an accident in the middle of a bar fight?
Or did they think the audience weren't smart enough to pick that up because the characters we're using words instead of juvenile high school antics?
You ever get a second chance to make a first impression. . .Uhura's first impression of Kirk were quite bad. . .He's drunk, he's hitting on her, he uses the "talented tongue" pick up line. . .but Uhura probably would have forgiven him for the accidental tit grab if he hadn't LEERED at her. . . it was only then that she pushed him back into the fight. . . as for the "high school antics" the characters are young . . Kirk and Uhura are 22, 21. . .people who are young do things like that. . .
