What a waste of time

I ordered a video intercom on Saturday and was told that the order would be placed on Monday and the item should be there on Tuesday. On Wednesday afternoon when I went there the stock had not arrived yet. What makes it worse is that it took the guy 40 minutes to finally tell me that the stock had not arrived. He left me at the counter saying that he was going to check whether they had received the stock and came back with items for other customers instead.
