Similar dilution of benefits at other brands of other chains as well. Best to just stay where you want to stay/best value for you. Loyalty is not what it was before. The industry has changed.

I've seen tip jar at various hotel breakfast set-ups of all chains. Not a fan of seeing cash around raw/exposed food; this is not sanitary. But the restaurant industry is driven by tips in the US and at these self serve hotel breakfasts this is basically the only way for that staff to solicit tips.
