I saw a tweet on twitter and he was asking if "toll fee" is correct because it is "redundant". I am unsure about the answer because here in the Philippines, we tend to, sometimes, double the noun -- the same with the double negatives Americans do. I then searched whether words like "charge fee" and "tax fee" exist and there was nothing to look up for -- at least not "tax service fee". Is it correct to consider the word "toll fee" or it depends on the Linguistics of our country?
Yes, it can be correct. It would usually refer to a fee charged for a toll generally paid by someone else.
Anecdotally, it also appears to see some less common colloquial usage in the redundant sense, similar to "ATM machine" or "PIN number".
