I have shops from December and was expecting payment today. Nothing yet.
I still don't understand why people seem to be put out when they haven't received payment before the 20th of the month, but I can see why we get nervous when the 20th comes and payment isn't there. I don't think I've ever received payment later than the 20th.
I learn something new every day, but not everyday!
I've learned to never trust spell-check or my phone's auto-fill feature.
