Mark&janice, it's not a problem & no offence taken. I am a serving police officer & I have never arrested it dealt with someone for said offence & put simply .... I wouldn't!!! I cannot fathom where in the legal definition of theft it would come under as how would you determine who 'actually owns' said rock. Ergo, no injured party .... No theft!!!! But hey, I work in the town until recently so shall bare this in mind. Although, think I definitely won't be adding rocks, etc into my tank. Not that I may get arrested but I've seen what some people do on a beech .... Yuk!!! .
That aside, no offence intended or taken.
Case closed (pardon the pun!!!! Lol)
Oh meant to add, apologies about the spelling hence I can only summise that you are not using an I-phone!!! The predictive text is ridiculous!!!
