going through an entire tray of liqueur chocolates and slurping the centres.

Hee, this is exactly what I get. Ripping the foils off a whole tray of 'Famous Names' that someone got given by their granny at Christmas, biting the teeny weeny 'bottle necks' and pouring the yummy cointreau/courvoisier/whatever down his throat and moving on.

I may possibly have done this some desperate Christmases!
