To me it is the culmination of things.Yes things happen-and it is nice when they are fixed quickly-but 4 things going wrong in one weekend?Sorry but I would be upset also.
Again I ask-why should we have to work/worry/be bothered by such thing on our weekends?When my leisure time involve dealing with other peoples screwups/mistakes/ineptness then that is to much like work for me.
And I will state-at the risk of sounding greedy-that I expect compensation for a weekend ruined by someone other than myself when proper training/maitenance/concern would have prevented the ruination of my leisure time.
