First I will say, I am very much against dark patterns and I believe servers should be paid a fair wage and not have to rely on tips.

But until that I do tip for dine-in service. But I found the "buy me a coffee" link on the button of this to be much funnier / ironic than it probably should have been.

It's also missing what I think is the worst dark pattern:

Having no option not to tip at all. Instead requiring that the customer press "Custom" and manually entering "0.00"
