Don't: Eat and drink while walking down the street
Tabe-aruki (literally ‘eat and walk’) may sometimes be convenient, but it’s considered a social faux pas. Even if it’s a rushed grab-and-go breakfast en route to an early morning meeting, a well-mannered person will demolish their croissant and sink their coffee in front of the shop where they were purchased. That’s why food stalls, vending machines and convenience stores are surrounded by standing snackers consuming food right there and then. Furthermore, these outlets all come with bins helpfully attached – and with tabe-aruki considered uncouth, the need for street-side trash disposal is dramatically reduced.
