Yes take it and do what I did mate.
Get a mini digger if you know how to use one, if not find someone that can and sort them a drink. Being at a pub there must be someone who can drive one who drinks there!!
Scrape the whole plot if it's fairly short grass/weeds (or strim 1st if not), dig a couple of big holes where you want your beans to be and bury the lot at least a foot from the surface.
It'll all rot down and apparantly the beans will thrive on it.
Mine went from this (108ft long by 15ft wide)
To this in a matter of a few hours
And if the pub wants some of the produce, get them to buy all your seeds
