Name a reason a cab driver might say he had a bad day in job?

According to family feud:

1. No fares

2. Bad Tips

3. Heavy Traffic

4. Got robbed

5. Got a ticket

6. Flat tire

7. Accident

They could keep getting lost, count up change wrong, they could keep farting when people are in the cab and they could drop people off at the wrong places
no fares
 got robbed
flat tire
bad tips
heavy traffic
got ticket
accident
A perosn riding with that cab driver could have said something mean to him about his job.
