Well if they're buying gasoline in California, or cigarettes in Australia taxes can be a huge part of the pricetag even if they're not thinking of it as taxes. You can see various taxes and fees if you look at the receipt of an airline ticket or a bill from a Telecoms company.

First off there is payroll tax.
Then there are sales taxes.
And don't forget property tax.
I am probably forgetting something.
