I use cash for:

1) paying my maid / house help

2) buying drugs

3) tips at restaurants / hotels

Also often traveling to 3rd world countries / somewhat corrupt locales. In these cases I make sure to have cash for bribes when the police invariably decide to shake me down.

1 and 2 are easily covered by adequate bank services, 2 is covered by bitcoin.
