Congratulations for established such big bar in your environment but the step you took to introduce BTC in your bar, I don't think is a good idea and it will land you for trouble because all eyes will be on you that you use BTC to establish the business not knowing that it is your father that supported you with the capital.

 Since some of the things you are selling are drinks, it will be difficult for people to ignore local currency and use BTC to pay for the drinks and the high rate of dollar in your country show that it will affect your profits if you introduce such payment in your business, but I will advise you to be saving some money in BTC so that whenever the price increase you can sell to buy more goods in your business.
