It was $5 cheaper to take a 333-3333 taxi than to use Uber or Lyft. Have I been sleeping on the taxi company?

just like it sounds. I took a Taxi home to Briar Creek from RDU around midnight and Uber and Lyft both quoted me $20-25. the Taxi cost me \~$16 and was just under $20 with a 20% tip.

I don't go out a lot anymore, but is this fairly common or just a one off where the taxi is cheaper?
