Unless there's something I'm missing, I don't think you were entitled to any compensation either. You seem to have two complaints that you believe merit compensation:

1. Lack of choice of welcome amenity (points or F&B credit). Yet you did select the points (automatically) by using the mobile check-in and the instructions were clear that you needed to initiate a conversation to change from that to (presumably) a F&B credit. You didn't, so no compensation due.

2. No mention of lounge access or alternative upon check-in. Nowhere that I see in the T&C provides for compensation if your options aren't mentioned. It's due if they're not offered. I know we're quibbling a bit here, but if we play gotcha with the distinction of whether they say something on check-in versus say no when you ask for what you are entitled to, I agree with the earlier poster that's not going to end well for us. Your post doesn't say so, but I infer there either is no lounge at that hotel or it was closed/unavailable. In that case, the T&C say you're entitled to daily continental breakfast in the restaurant or 750 points (not a F&B credit). It sounds like you didn't use the breakfast option for whatever reason. You were not entitled to a F&B credit to use whenever you wanted. So no compensation due.

The rest of it sounds like a miscommunication between you and the MOD about F&B credit as service recovery, not as required by the T&C, so no compensation due unless the hotel wanted to do it as a goodwill gesture.

Sorry, but I think you were asking for something you weren't entitled to under the T&C.

(Edited to add: what about the scenario of mobile check-in plus mobile/electronic key - in a scenario where you never see the FD, what are they to do? Automatically pay out because there was no conversation at all?)
