I don’t think so, tips are for service and moving my bag of food from the shelf behind you to the counter in front of you isn’t service, that’s just your job. I tip waiters, bar tenders, and drivers (delivery, ride share, cab). That said I’d love to get to a point where we can largely get rid of tipping by forcing full wages for all jobs and not tipped wages.
Add in the congress critters from both houses need to run their own campaigns at some point, in many cases they can’t afford to just kiss the ring. This is especially true in the house where seats are up for grabs “soon” and the voter base is relatively small. If you’re a Representative and won your seat on a small margin, you clearly don’t have a mandate and need to act more moderate. Some senate seats are in the same boat (McCormick in PA, assuming the recount still favors him, is in this boat; he’s run three times now and barely beat out Casey this time, it’s a fair bet he doesn’t have solid footing for his first term and can only toe the party line so far). The only thing we should all bet on is at the end of the day everyone in politics is going to lookout for themselves first. It’s going to be a shitshow for at least the next two years, probably the full four and maybe beyond.
