If It does sound like if they "cant explain it" - then they may indeed be applying the calculation wrong. In otherwords - it may be a simple mistake.

I have received incorrect bills every now and then, and if I feel like it is anything to be worried about, then I do the calculations myself. If the bill is wrong, I simply show them the results and always end up paying the correct amount. But to be honest - in the situaiton described above with the coffee - I wouldnt think twice about paying either $120j or $140j cause I would probably give them $150j and say keep the change... at most we are talking about an error of twenty cents in us$....
This isn't about what you would pay or I would pay we had 2 cups coffee and left them 500J's. The point is they beat the J's up its no mistake . Lets say old days red stripe 1 U.S. dollar or 50 J's with street rate of 60 to 1 they never pull out calculator, you say paying in J's they say give me 50 you say U.S. they say 1 dollar. you make out paying in J's be it 10 or 20 cents its adds up over days. Now days street rate 80 to 1 , buy something priced at 10 U.S. dollars it should cost me 800 J's but they say no 950 if paying in J's. Now tell me that's not beating up your own dollars? So when you pay them in J's the rate is 95 to 1 but they tell you no. Like I said this happened more then once and at more then 1 place. You can walk to most beach places order 2 beers and they need get the calculator to figure out how much in J's . That never use to be like that even when prices where in J's. I see it as A calculator beaten not a mistake.
