i have a solution to the argos problem ... dont go in argos. It works for me.
on your general point though, i agree sometimes yu just wqant to cry for example when i was in mand s cafe the other day there were 4 people clearing tables, yet none of the tables ever seemed to be clear .... when i was waiting for my cooked brekkie in tesco, there was a 15 year old taking the orders, putting your stuff on to the plates then telling the egg cook how i wanted my eggs, leaving everything else to go cold on the plate whilst they cooked the eggs.... how angermafying! (especially as all the people had to then wait behind me, have these people never hard of systems of work????)
