No offences, Just wanna ask why not just send the payment immediately? why should wait?

maybe he is busy with his other work or its not his working time
usually they complete the work in the order they received, not just do it randomly
I received the list late at night and was not home. I thought I would be home today but I'm still away, I will most likely (99%) be home by tomorrow and payments should be sent then or before. Sorry for the inconvoenice guys.
