But if you have time to add, the blue one does the same, except it fills the bar to the max with just a click. No matter if you have 3 mins to add or 60. Minutes seem to cost the same no matter which button you use too? So I don't get how you're saving money but using the gold one. If you top off your drinks, you can time them to sell in an hour, and since you don't need to be at the site for this to happen, I don't get why you'd want your tender to work 10 mins and not 60. That's obviously less money, especially if you only have a few mins to play.
Does it change after level 1? Does the blue button only allow you to add up to 60, and after level 2 (where you'll have an additional 60 mins), will you have to use the gold one to add mins past 60? There's totally something I'm not understanding. I'm probably overthinking, but this type of game is my thing, I make it a priory to understand.
I suppose in a few weeks, I learn its use. For now, the blue button seems much more efficient.
The +10 mins button is a great advantage. Last night when I wanted to hit bed, I restocked my warehouse with 50 beer.
For the bartender, he had 20mins left to work. I had the option to to top him off to full 40mins or 10mins.
I used 10mins thrice to get 30mins which will make him work 50mins for the 50beer in warehouse.
If I had to buy only the 40mins then I would have had to face a loss of 10satoshi.
Also, though it may not seem to be obvious, you almost always loose a few seconds when you refill the bartender using the blue button. I may be wrong on this but this may be the case if for example, the bartender has 20mins 30 seconds to work and the blue button shows 40 mins. You loose 30 seconds work.
