As we reported earlier this week, the District of Columbia arranged with Metro to open the rail system an hour earlier than normal this morning, at 4 a.m. instead of 5 a.m., in order to accommodate shoppers looking to be the first to arrive for early bird sales on “Black Friday.” Metro spokesperson Lisa Farbstein emailed to let us know that 2,287 people rode Metro between 4 and 5 a.m. today, and that the cost to the city to pay Metro to open early was $27,000. That comes out to the District having paid $11.80 for each early bird rider. Given that today is also a tax-free holiday for shoppers in the District, that $27,000 is money the city won’t make back in sales tax revenue, either.
