We often come to this McDonald s but then there, anthology.
We arrive at 5:45 pm, the doors are closed, after reading the 45 signs on the door we finally manage to see that if the doors are closed you have to ring and someone comes to open you. What we do. Once. Twice. Then as the saying goes, never two without three. No one on the horizon.
Out of whom do we see through the glass of the doors? Someone in the kitchen who obviously seemed too busy to come and let us in. Ah yes ! Did I tell you that the restaurant was empty at the time? Yes, way too busy.
We wait, again and again. But no, it seems to be far too difficult a task to come and open a door.
If you don't want to welcome a client, then why stay open? Simply close it will save you wasting time and making us waste our time.
