Have you got the App? Have you done it yet? Have you tried Uber?
I haven't personally, but I've heard nothing but good things. Especially if you've been drinking. And even if you've only had a couple of beers, you could be over the legal limit. Why take the chance?
Plus it's cheaper and significantly faster that calling a cab.
Need some extra Christmas cash? Uber to the rescue again. As I understand it, the money you make isn't huge, but it beats working.
I haven't tried it yet, but plan to very soon.
