heh, reminds me of time I forgot / didn't care to file a quarterly GST (fed sales tax in Canada) return. Little while later, get a letter from Revenue Canada in the mail, telling me I owe them EXACTLY 7% of all deposits to my business account during that quarter, to the penny.
I was pissed off at the time. Who the fuck gave you guys the authorization just to go mozying on through my bank account transactions like that? Fuck off. I only owed them maybe 3% of the amount anyway, because majority of customers weren't Canadian residents. Only way they could have came up with that exact amount though is if they had full access to my bank accounts.
I had a mom for 18 years, and that was good enough. Don't need a big brother for the rest of my life, but thanks anyway.
