    I have ordered SF vanilla ice coffee three different visits. The 1st time I ordered I waited and was told we don't have it and waited to be refunded. No apology from the manager. The last two times it tasted terrible. Unable to drink. I just threw it out. Obviously no training on how to make it. I now bypass this lMcD.

    They lost my food on a busy Friday night. I waited out front for a 15 minutes then road back through. The drive through guy (red beard) was super apologetic and helpful. Did me right, and fixed everything

    Literally never have shakes or ice cream supposedly which is like whatever that's the stereotype with mcdonald's, but I am a doordash driver and when I came through the drive thru after 11pm because the inside is closed they literally said "what do you want" and when I attempted to speak and say "I have a doordash order for (blank)" they interrupted me before I had a chance to state the name even and didn't even say please pull forward they just said "pull to the window" very rudely. it is consistently a male worker in there who is extremely rude to customers for no reason. I am very kind to workers and always speak in an upbeat tone and say "please" & "thank you so much" not even just thank you. It is unacceptable to be rude to customers for no good reason especially when they are showing you kindness out of the gate. I have personally worked in fast food before and i don't know a single other business that would tolerate this kind of behavior, something needs to be done. This is why everyone drives out of the way for the Harvester location instead.

    This was at 2pm and it took 30-45 min to make it to the pick up window. The gentleman taking orders was not trained, I was put on hold then had to repeat order then on hold etc. The food was cold and I had to throw it away. Waste of time and money. The new chicken strips were terrible, but hey we’re cold and dry. Get things right!!
