I don't particularly care when they do this - reminds me of high school "spirit week" type thing. BUT - I do hate that it has the effect of making jersey-wearing fans entitled. Have experienced a few cases (even well after the promotion had ended) where folks in jerseys storm the gate area at pre-boarding stating they're in jerseys so they get to board FIRST, throwing mini tantrums when they're told its no longer happening, or that they need to wait until the jersey boarding group is called. Would be interesting to see a venn-diagram of jersey gate stormers vs non mask compliance, but it might just be a circle.
