Being rushed to order

took my girlfriend to get ice cream went into the drive in where the cashier asked me what i wanted then i ordered the ice cream, then we took a little while to see the menu when the cashier thru the pa system tells me to come thru to the window and i can place the rest of the order there. we then asked for a while whilst we looked at the menu , then in a bad tone of voice it sounded like he was shouting at me to come thru to the window to place the rest of my order. So if I come to the window how am i going to see the menu to decide what i was going to order next???? the attitude of the person was bad an this is something that needs to be sorted out. I drive 10.1kms to mcdonalds to come be rushed into what i order and spend my money??? Am i gona get a call again saying they sorry and nothing is being done about it???? I hope that mcdonalds looks into this cause i love mcdonalds i eat it atleast twice a week and this just goes to show that they are losing they touch......kinda sad thinking that i must find a new favorite place to eat cause of bad service...
