my guess would be that those loyal customers are the least likely to leave, so u can squeeze as much as u like out of them.
new customers u wanna attract more of, so treat them better and they will come to u.
those who leave and come back for the discount are probably not a meaningful enough size for a company to even think about.
Or even worst, the elderly?
id say this is definitely an effect of this behaviour, but i doubt its intentional. a company doesnt care abt anything but profits, so they dont care abt the impact of their actions beyond that





this “common knowledge” “weight loss” stuff typically neglects how dieting will affect ur caloric rate. if u just starve urself, ur muscles will grow smaller and u will need fewer calories to maintain ur normal functioning body, meaning u need to eat even less again to not put on fat. but if u train ur muscles directly, they will beg for more calories so they can grow, and the calories needed to maintain them will also increase.
for anyone interested, i suggest reading a physical education by casey johnston.
