(In)ettiquette?

Let’s say hypothetically I’d been working at my job for 6 months, and I just got a raise.  Let’s say hypothetically I work for a rather large company where things like raises have to go through multiple chains of command, all the way from my boss to her boss to her boss to her boss, and so on and so forth.  Let’s say hypothetically my boss discussed my evaluation and raise with me in the middle of February, never indicating what it would amount to, and I’ve been waiting around for news of this raise since then.  Let’s say hypothetically that I took a look at my most recent pay-stub and determined that said raise was finally approved.  Let’s say hypothetically that said raise amounted to an increase of 2% over my previous salary.  Let’s say that hypothetically I was told the reason the raise was the amount it was is because I’ve only been here for 6 months. 

Is it safe to assume that hypothetically a “normal/regular” raise for this company would be 4%? 

Hypothetically, is it bad that I didn’t sound too enthusiastic when my boss called me to inform me of said reasons, even though YES OKAY IT’S AN INCREASE IN MONEY, but hello, the amount it comes to after federal and state taxes, social security, and FICA take their chunk, makes it mere dollars?!  Plus, let’s say that hypothetically I’ve been kind of shafted from the get-go, since my job duties were very much under-represented in my interview process and I’ve been responsible for much more work than they had initially suggested.

Have I shown bad ettiquette, ya know, HYPOTHETICALLY?!

Ugh.
