Most businesses of all sectors use all kinds of techniques to maximise consumption from customers, some of them very shady. Billions are poured into behavioural studies of customers and voodoo tricks so people spend money on stuff sometimes they don't even need.

As a customer, I feel entitled to take advantage of everything I can. I don't understand the negativity around it. Us consumers have a salary each month, and we are supposed to get everything we can out of it. It's that simple.
