Mugg and Bean Kathu dishonesty

I just had a breakfast at the Mugg and Bean Kathu and when I went to pay, the price for the breakfast was more than what was on the menu. The waitress gave me the lame excuse that the difference in price is because of Covid 19 and they haven't had a chance to print new menus. The price of their coffee is also over inflated. The owners or manager have lost touch with reality !! I won't eat at a Mug and Bean again because of their dishonesty.
