Two Questions ... are most places okay with running you a tab when you just drop in for a couple of hours and then settle up with cash? and more importantly while staying at CFS and CCLP will they let you to run a tab every day during your stay and pay by credit card at the end of the week (of course a cash tip would be left every day as appropriate) and if so, any hazards in this other than the obvious.

ps ... having read this board for a while I am sure there will be lots of responses suggesting that tabs are perfectly acceptable as long as you guys are there to partake in the refreshments
