Coffee day is expensive

Coffee day has revised its pricelist since last month. One of my alltime favourite 'Cappuccino' that was priced Rs. 30 now costs Rs. 45. Its a 50% jump straight. I think its either planning an IPO (to show good balance sheet) or the costs have gone up really high. If we say, costs have gone up high, milk did not really go up so much in the past one year. Fuel prices have come down, the number of people visiting coffee day did not go down, the staff remained same, rentals would have been agreed upon before and one could expect a rise of about 10% max in a year. Salaries would have gone up by 15% more. Total expenses would not have rised more than 15 to 20% considering the above facts. And finally coffee prices. Weighted average prices of coffee in the last three years did not change much. I understand there are fluctuations, but as I said overall in a year not much of change (google on coffee prices). But a straight 50% rise is a surprising move. I would be consuming less coffee there.
