I enjoy punting on fridays. Maybe its the thought of a day off the next day.
Wednesday seems to be the day for me at the moment, though not today as nobody local took my fancy. Friday is sorted though!
As for punting traditions...triple checking the cash En route to the punt. Making sure my phone is on silent. And I always have a shower when I arrive, irregardless of whether I've had one before I leave...I'd rather they know I'm clean than just taking my word for it.
