At the beginning of Peak, and on the first day you get a helper, this is one of the things that needs to be cleared-up. Some drivers want their tips, and rightfully so, so they should make it very clear to their helpers that any envelopes handed to them are theirs since they delivered there all year 'round. Me personally I let the helper(s) keep any cash tips we receive. That money isn't making or breaking me, and it's always a nice added bonus for my helpers. They don't make much to begin with, so anything I can do to help them during the few weeks they're with me is a plus.
Anyway, funny story. Hope that $10 was enough for the bus ride home. I've kicked a few helper turds off the truck mid day because they were utterly useless, and started arguing with me over how heavy packages were. 40 lbs is NOT heavy. Can't lift it? Beat it.
I know times are tough but I averaged about $800.00 every Christmas on my 85% country route in my years of driving. Sorry, but I'm not handing over that kind of money to a guy who'll spend maybe a month with me out of my year of breaking my back.
