Really weird this, never experienced it before; only just started happening (since I bought a new pair of shoes maybe?).
I go to the sink (ceramic) at work, grip the tap (metal) to turn it on... water pours out and goes down the drain, not surprisingly. (With me so far?).
I then take my hand away from the tap, and as it touches the water jet I get that same slight but distinctive 'zap' I usually get from the doorframe as I climb out of the car. First time it happened with the water jet I thought I'd imagined it, but the effect is definitely reproducible.
How is this happening? (and does it mean that there's no supplementary earth bonding on the plumbing at work?!)
Thanks David
