Either Mister took the whole incident as a flimsy excuse to abuse or he's a bit too zealous about punishing'em
Either way is fine, though that means Chen and Show should pay attention to what they are doing since the smalles mistake may lead to mister hurt hurt, mister hurt hurt everywhere!
yeah, still a bit hard to tell at this point but either the anon is a bit dumb (accessory fell off by mistake, he honestly thought chen was puffig at shou for being accessoryless) or he's an abuser (he took the accessory on purpose and chose to misinterpret the puffing in the name of being the good guy)
