Shanghai Bandit

The first time the bank gets robbed, it's by two separate, unrelated parties--at the same freaking time. But when a robber has a stroke on the job, everyone comes together to help. Bank teller/Vietnam veteran major Chin volunteers to take the poor fellow to the ER, and while he's at it, assist the other criminals in their escape. On the way to the hospital, while Chin and the criminals share a moment of bonding, the stroke patient recovers and hijacks the take.

The second time the bank gets robbed, one of the robbers is major Chin, for he has planned a perfect heist.
