Why does a stranger lend Akira pants?


During the first episode, we see Akira running down the street without pants.
Then he asks a bystander, and the guy just lends his pants to Akira. Is this
related to some cultural reference, or is it never explained and is a strange
plot element even to Westerners?




It's never explained but I imagine that Akira transferred him some large
amount of money from his phone. The man is clearly elated at whatever Akira
offered him.
