Row houses maybe, but there’s an adversity to condo fees which usually come along with every other source of housing. A lot of people want to feel like they own their home outright, so that once their mortgage is done being paid off, all they need to worry about is the hydro, water, and property taxes. There’s a lot of stories about condo groups doubling condo fees that put others off those types of places.
Seems to me like the reward was free gas.
If you’ve developed your system that the rewards card can provide a bypass to free fuel, your system is the flawed one and it isn’t on the customer to provide feedback. This isn’t a user testing scenario, they should have solved this bug before it went to production.
People aren’t responsible for cheaply built solutions.
