Summer job as a lifeguard for the outdoor pools in Portsmouth when I was 18. Particularly that it was
- outside
- paid around £8 an hour which was good back then
- council rules meant you worked 30 mins on, 30 mins off with full pay for the hour
But mainly that the 'pool' I was 'lifeguarding' was 1ft deep at the 'deep end' - it was the kiddies pool as the main lido was closed

So basically the job entailed lounging in the sunshine for half and hour eyeing up the yummy mummies, then taking half an hour off to lounge in the sunshine elsewhere, punctuated occasionally by having to walk into the pool to upright a toddler who'd fallen over or putting plasters on banged toes.
Was awesome
That said, I may be trumping it with my upcoming job, which is a summer working in a California Beach State Park, basically lounging in the sunshine helping out generally with tourists on shifts of 7:30-2pm or 3pm-10pm, meaning the mornings or afternoons of those days will be spent on the beach surfing and lounging around. Damn I like these summer jobs
