My first ever job was in retail.  I loved it!  Having grown up in the country, treks to town were rare (aside from going to school ... and that didn't count!) so to be able to spend all day every day around shops and merchandise and interesting shop people was heaven.
One of the jobs I longed to do was to sweep the footpath.  I know - it sounds ridiculous.  But I so wanted that job.  Why?  Because the boss swept the footpath every single day and it took him forever to get it done.  I was convinced I could sweep soooo much faster and better.
What I was missing (at my tender 'know it all' age) was why he swept the footpath.  It wasn't necessarily worse than any other piece of footpath outside a shop.  In fact, given my druthers, I'd probably have swept it twice a week.   Job done. Time saved.
