If you do, it is simple, Guy1 has the booking and gets priority.
If you do not, it is still simple. You tell Guy2 to come at ten past six. Then at ten before six, you contact Guy1 to see how he is doing. If he says that he is just looking for a parking spot, then you can text Guy2 and cancel. It's not great for Guy2 but it is a lot better than hanging about on a cold street corner phoning phoning phoning.
