Valid point JohnDoe. If I've been married, I probably would have been known as 'Puntman', because I might have been showing up with a 'Batman' mask when ever I'm taking my tottie for a treat.
Small world really. You can walk into anyone whom knows someone that can cause some damage to your life.

But yes, I've never really bothered much when walking into a punter. Like it's been said, those whom you walk into can't really judge you!

What if mother in law is deceased - you do not have much on father in law then

I think this depends on the type of venue it is. The venues with a bar / entertainment- I have noticed that punters are a lot more chilled and carefree. If you go to a venue then you must reconcile yourself with the fact that you might bump into a punter, irrespective of whether you know the person or not and despite what the venue says because mistakes always happen. But bumping into someone (punter or not) at a lady's private apartment/house - now that changes things.
