Nobody asks for the shop address any more. Everyone turns up on WhatsApp. Orders there, questions there, complaints there, and the payment screenshot there too.
The problem is that all four land in the same list. Somebody's 'what are your timings' arrives in the middle of an order, a screenshot under that, and under that the person asking for the third time where their stuff is.
You read top to bottom, answer three, and the fourth slides down. By evening it's 40 messages down. It wasn't missed — it got buried, and nothing notifies you about a buried message.
So the question isn't who is going to reply. It's who is sorting the inbox.
