I'm of the same opinion, they're working for minimum wage or near enough to it, maybe just being nice to them will make their day a bit better. I've worked those jobs, and have been abused for an incompetent (or lying) boss. It's not my fault, please don't scream at me. One guy did shout at me while I was out on a job, and then when I finished he gave me a bottle of a nice wine by way of gratitude for the work done and apology. That put a spring in my step (even if I don't drink wine). Be nice to front line staff, because as you say, their lives suck.
