Your RFB or RFL status has rules attached. Always find out what they
are to get the most out of your "perks". There may be dollar limits.
Sometimes, however, there are "people" limits.
Example: Paris offers me RFL. It is based on TWO people. So, when I go
into the Boulangerie and buy my $75 worth of pastries, breads, etc to
take home I make sure the cashier rings it up as either 1 or 2 GUESTS.
Their system doesn't care how much I've spent - it tracks by guests.
Believe it or not, you can walk in with two friends , order three
coffees and spend $10, have it rung up as 3 guests, and the computer
will only take off 2/3 of it, putting $3.33 on your bill. Yes, you can
spend 15 minutes finding a host to take it off, but why go through all
that?
Spend $80, ring it up as 1 guest, and you're fine.
ALWAYS at checkin find out what applies to your RFL/RFB and how it is
posted. And do this every trip - don't assume it will be the same as
last time.
