I like having a little control over the reward a server receives. At the DMV I have no control and get treated like dirt. While tipping for all services might be impossible and way to complicated it seems like I get better service when a TIP is possibly in the mix.

Depending on the establishment and the server’s performance a server can make GOOD money. My wife was a server when we first got married and made decent money.

Some servers do not report all the income to the government so much of the TIP is tax free.
