There are currently 107 jurisdictions in Alaska which charge sales tax.  Quite a few of them
charge sales tax on food from grocery stores....That is why I was replying to your statement 
in which you said 
"You do not pay sales tax on food, unless it's when you eat out."
Plenty of Alaskans can tell you that you are wrong, and they DO pay
sales tax on groceries.  I understand that a large part of the population of Alaska
lives in Anchorage and doesn't pay sales tax, but that doesn't make the statement
"You do not pay sales tax on food" a factually correct one.  I am among the 
thousands of Alaskans who pay sales tax on my groceries.
