one small thing i noticed that has nothing to do with animation was why would he have both hands grabbing way up there for the metal pole, and why wouldnt he just take one hand down when he went to sneeze? i cant remember the last time i saw someone actually sneeze directly on someone else. other than the logic issues, the animation itself looks good. more hold/anticipation right before the sneeze could help.
edit: also, i think this topic might be suited for the 2d section.
it happens often depends on the country and the status and the common rules if they know how to move in the public but i saw a lot people doing exactly that...
i like it, simple characters but they have enough to convey emotion. i get a good sense of that and especially like the last bit where he sheepishly wipes off the other man...
