I don't see anything embarassing about those jobs. Your life and mine depends on sanitation workers.
Any honest work for decent pay is a 'good job'. Sneering at those that do the difficult and nasty jobs that keep us alive is contraindicated.

I asked my collectors once what their pay was. They told me $22. per hour plus time and a half for over time, that was a couple of years ago and they are not union.
I always tip the two of them around Christmas time. If a raccoon gets in my garbage, they pick it up off the street for me, that’s not part of their job. That alone is worth the tip.
