Sure, I would characterize the exorbitant fees on a "per interaction" level. As another commenter mentioned, a large deal can have huge fees associated (and much of this is about how big the term sheet is and how many minute details are involved). Some of this can be mitigated by requesting a very simplified term sheet from the VC/angel firm you are working with, but what bothered me more was the costs for small asks.

What I found was that with some lawyers, every email and every phone call (no matter how short) will add hundreds of dollars (emails are rounded up to 15 minute increments). Thus, whenever I can, I try to negotiate a fixed fee to get a particular item done (incorporation, fundraising etc) and then I don't have to worry about every minute of time and what that translates to in dollars.
