Bad service and nevermind attitude

Was at hungry lion yesterday, trying to buy some ice creams. So I had a two hundred note and was told by the cashier that she does not have change and she will be unable to assist me. So then I asked for the supervisor or manager who is in charge of the shift and then the Manger/supervisor then told me the very same and also added that if I wanted to be assisted I should go outside the shop and ask for change at the taxi driver. Was so surprised also with the attitude that I got from the Manager/supervisor she gave me a nevermind attitude,which is bad for the franchise and as for the experience I got I don't think I will ever buy at that branch again.
