Ah must've been a few verbs missing. I don't see anyone who said that, though. There was a reference to $28, which is the monetary value of the credit provided at a specific restaurant. For a $99 annual fee, anyone can buy a standard Priority Pass membership, which allows you to enter lounges, including the Marhaba lounges, for $32 per visit.
Few lounges charge $25 per visit, for sure, but also a day pass purchased with a lounge directly frequently includes more than a Priority Pass visit - often in the f&b department, but also sometimes no length of visit restriction.
