run a tab
run (up) a tab
To incur or accumulate charges that one must pay at a later time or date. It's a bit hypocritical for these politicians to be pushing legislation that raises the price of alcohol, while they're all there running up huge tabs at the parliament bar each week. Don't worry about the cost of anything while you're here; I'm running a tab with the hotel.
