You see Becky and Marion, people like me tend to remain silent during any such occasions. Like I said earlier, people who let themselves down (I'm not talking using wrong knives, cutting pizzas into cubes etc) don't realize how stupid they appear. You can bring a person out, dress him/her up, buy a beautiful meal, supply entertaining conversation etc and then you smell their body odour, listen to gnashers munching loudly and conversation that would have a docker duck and suddenly the prospect appears like the source of unwanted entertainment for the subtle well behaved.
There is nothing snobbish in this. Once again, I reckon there is an opening for some cultivated person to make a few bob here. People pay for interview techniques and even the presentation of cv's. Money wasted if you behave like a starved dog gnawing at a suddenly presented bone.
