If the sound engineer can't sort out the drum sounds in under ten minutes then they can fuck right off.
I've worked as a live sound engineer and drum sounds aren't that hard. The only time they are hard to sort out is when the kit isn't tuned and that's the drummers problem not the engineers. you just can't EQ out shit.
The problem with most engineers is that they try to play the part of the producer as well as doing the sound engineering. Big fucking mistake! The sound system in any venue is only there to reinforce what is happening on the stage. The other problem with engineers I run into is that they are generic clones from some fucking audio engineering school that taught them how to work with super-groups in the studio but not how to deal with real bands in a real live sound situation with average equipment.
And of there is the last part of the equation which is the band. If you play on the stage like you do in the garage at practice (so everyone can hear each other) there really shouldn't be a problem a sound check.
