Mick the plumber

I can't work out the plug in the sink in my hotel room. There is nothing to unplug it! I've pulled it, pushed it, fiddled with the taps, everything! The only way I've found to get the sink to empty is to run the tap and let it trickle down the overflow.

After an extensive chat with "Mick the plumber" last night, where we discussed in depth the different ways of resolving the issue, it transpires that the best we can come up with is to empty the sink using the kettle in the room. Maybe the cleaner will fix it today.
