You are telling me. That's why I usually don't "slap that ask" daily but rather just wait and hit it in one big "slap".
Thankfully I don't do that many OTC stocks (currently 4) and from most of them if I call them they push my commission down from 500 to around 50-60. I mean, compared to $6 it's still bad but it's either that or nothing for me at the moment. And that 50 is well worth for Viva. But calling them each time gets tiresome.
