[Tagging] Feature Proposal - RFC - Top up

I find "top_up" alone highly misleading and unspecific.

I encountered the term in filling stations, where you would order either "5 gallons" or "top up", 
i.e. to fully fill the tank. Or when pre-paying the fuel, you would either pay "fuel for $20", or 
leave your credit card with the cashier to allow "top up".

In the same sense, you could ask the bar keeper to "top up" your cocktail glass.

In the context of pre-paying credits for phone or transport, there is no such "top", no upper limit, 
you could buy any amount you want. Thus this marketing slang is misleading.

It is unspecific to be used in OSM since it does not indicate which service is being paid for.
Using it on the object tagged with amenity=bar it gets absolutely confusing what is getting topped up.

Thus, I'd not use the term "top_up" at all, and as Martin proposed, indicate the type of service 
first, e.g.:

Even 'credits' seem problematic, since what you pre-pay is not a credit.
