I can understand your frustration, with the amount of time and effort required to create a cache. Maybe some people just don't realise how much work is involved?
Even as a newbie myself (10 finds) I appreciate the work required and am looking forward to the day I create my first cache :-) I hope people would be courteous enough to say thanks when I do. Maybe it just the world we live in these days, not enough manners I say!!!
As my parents always say "manners cost nothing" :-)
