Greyhound Bus Ride Was Uncomfortable And Inconsistent

I've took two Greyhound buses over the past couple of months, traveling to and from DC, and let me tell you, they were like night and day. The first one was decked out with Wi-Fi and comfy seats—it almost felt luxurious. But the second? Total disaster. It took forever to get where I needed to go, and don't even get me started on the seats. I swear, I could've had a better ride on a donkey cart. It got me thinking, though. How come there's such a huge gap in quality between these buses? You'd think consistency would be a given. I mean, I've taken budget rides in other countries that were smoother than this. Couldn't even blink without feeling every bump in the road.
