Very Poor Service from Stuff

I've been to McDonald's today . I'm writing this review just after I had this incident! I'm standing in the line to order milkshakes for 30 mins just to get this to be told when I get to the till the cashier is so rude. And mind you there is only 1 cashier over at the end of the month! Not only did my order take more then 40 mins but my cold drink up wasn't even filled properly. This isn't the first time I've experienced bad service from McDonald's in Belhar however something must be done about the unfriendly and unhelpful staff at this branch immediately!!!
