took an overnight bump (lax-sfo) on saturday night and ua took care of the hotel, gave me $$$ certs instead of the free tix ^ and a meal voucher. where the meal voucher was good for 24 hrs from issue, i figured i'd grab a bite on sunday morning before my flight back to sfo but to my suprise not one of the restaraunts in t-6, 7 & 8 i tried would honor it saying ua was slow in paying so they would not accept them anymore (and trust me, i tried a lot in all 3 terminals). we're not talking a lot of $ here ($7.50 voucher) but i just thought i'd share and wondering if it was bs from the restaraunts (kind of a gang "we just don't want to be bothered with them") or if others have had similar problems
