I ordered takeout through Deliveroo, but it was delayed for 40 minutes from the scheduled time. I understand that it was Mother's Day and some extra waiting time might be necessary, but when I inquired about the delay with the manager, I received extremely rude treatment.

The manager stated that the kitchen was already very busy, but if they couldn't complete the order within the specified time, then why did they accept the order through the delivery platform?

Afterward, he ordered the counter staff to stop taking any more delivery orders.

Furthermore, I noticed that he prioritized serving customers who purchased takeout in person, and did not seem to care much about customers who ordered through the platform.

Aren't delivery orders also customers?
