Adding PSV when you've already got HGV

If you like driving but don’t like the idea of working on your own all day and like being with people then yeah it’s probably a decent job.

But, is the pay really that bad? And if it is then why would anyone do it rather than work say in a supermarket? Or a bar? Or a hotel? Or in retail? Which ticks the same boxes, similar pay, working with people, but probably for fewer hours.
