McGrath, I guess if the pub is otherwise closed for business and there are just a few very trusted friends about, the Pup Prop could be useful. I'd want to make sure no one was wearing shoes. I have my own protective device... a hard shelled case.
Tip for new players:
If your instrument doesn't require the protection of a hard shelled case when not in your hands, throw it away and buy one that does. Keep your instrument latched inside it's hard shelled case any time you are not actually playing it. If you are in a public place of any kind (pub, festival, theatre, airport, wherever) keep your hand or at least a foot on the case at all times. When you walk over to the bar for another pint, carry your instrument with you safely latched in its case.
Trust me on this. I've seen fine instruments lost, stolen, dropped, kicked, doused with beer and otherwise damaged by failure to follow this simple rule.
Related rule: You're not Johnny Cash and you're (probably) not on television. Never sling your instrument over your back suspended by its strap from your shoulder. That is unless the cost of a replacement instrument is not important to you.
Don'tworry, be happy.
