There is certain time of the day when the customers are willing to wait a little longer while at others the customers are too impatient to wait. Like in the case above, the customer had urgency so he booked a dog-walker. Had it been evening or just a casual booking rather than the urgent one, the customer might not have been this furious.
Same thing applies to the lunch and the dinner. When the person orders for food online that claims to deliver one instantly, he expects it to be present in the said time. Never forget, ‘ A hungry man is an angry man’. For the working people, where every second counts, they simply cannot take any extra minutes of waiting time.
Again, when the order is placed for the dinner, the customer can wait a little longer since there are any other commitments left for the day.
The point made here is, delivery flexibility at odd hours is utterly unacceptable.
