Overall what I noticed is that tipping is a sub-strategy among others in the American shopping experience where companies try as long as possible to hide the total price charged to a customer. You can see it everywhere from various fees, taxations, and tipping. I am shocked that it is so difficult to know the final cost of things until the very last second. Tipping is just one strategy in the toolkit, but tech companies are deploying it everywhere now, it's hard to escape.
