The app culture gives everyone a chance to trace, track, and tyrannize workers — even in a pandemic.
I'm inclined to give 5-stars to any customer service person, or on an app, because they get dinged for anything less than 5-stars. I used to work at AT&T many years ago, and any rep who got less than a 5 had to be "counseled" (i.e. why are you doing a poor job with customers, when they clearly weren't). I considered a 4 to be a B+ (still very good), but that's not how the higher-ups viewed it.
I hear people say, "There's always room for improvement...I never give 5's." You are now adversely impacting people's potential employment. If they got the job done, give them their 5 and go on your merry way...you're not a professor, so don't establish a grading curve.
I order groceries online and pick them up. I think it might be safer for everyone than grocery delivery or going into the store, but not all groceries have that option.
I have been doing much the same, ordering wise. I've ordered from a local Thai place about three times since this started and I've been getting takeout form the pub across the street once a week. I've been cooking a heck of lot more. I've also felt guilty using the ordering app in the past, and even more so now. I try to tip well to compensate and am not going to complain.
Nothing has made class in the US and Canada more stark than this plague has, with the jet setters able to ignore it entirely, the upper class retreating to their vacation homes, the middle class pod people stuck indoors doing mental work for the corps, the working class stocking shelves and driving ubers, and the unemployed trying to scrape by as best they can.
