If the sound guy or company is decent they will have a decent DI option for you like a Radial or Countryman DI. A lot of sound guys don't like using the amps DI for many reasons such as noise, it's running post EQ or because the output is effected by the master volume control and your stage volume will effect the mix.
Keep in mind that just because they are taking the DI out of your amp doesn't mean that the bass tone coming out of the front of house speakers will sound anything like what you hear through your amp on stage. That signal is being routed through a board with a different preamp and gain structure as well as a completely different EQ then your head. It's then fed to PA speakers that are not tuned anything like your cabinet. So you are usually beating your head against the wall for nothing to get "your tone".
The best argument you have is making sure that the sound guy isn't giving you some piece of crap DI that is not equipped with a transformer. The transformer will protect your gear from any voltage that may came back to your gear and damage it. It's rare these days but you never know when a club or church has had some shoddy electrical work done a volunteer or a drunk brother in law who meant well in an effort to save money.
When I was in your situation I would offer my Sansamp BDDI to the sound guy as an option to a crappy DI box. I always carried a (still have them) a Radial J48 active DI box and a Radial JDI passive DI just in case they were adamant about me going through a DI.
