Meadowdale Mall McDonald's

Meadowdale mall McDonald's is has *** customer service skills. The serving ladies has an attitude with you when you ask them for assistance. We ordered a Oreo mc flurry and paid for chocolate sauce however it didn't come with sauce and the lady told us we had to pay again eventually after showing her that we paid she went to go add the sauce but then it came back in a liquid state ,you could pour it out like water ,so we asked to speak to a manager the lady that serviced us said she is the manger but yet there's no badges no name tags nothing. After a long dispute we got a proper mc flurry but this will be the last I come to this McDonald's
