yes, most banks will kick you with 4-digit sums going in&out daily
except you have a corporate account and some bank stuff license
I don't think it is so much about how much money you have going into and out of your account, I think the amount that you have going into and out of your account when compared to the total amount you have on deposit with them and the total amount of your income. If you make $300,000 per year, then it would not be unexpected to have $2,000 (or more) get deposited and withdrawn every week, but if you only make $50,000 per year, then $2,000 per week getting deposited is more then twice the amount of your pretax income.
