F* Up service from an International Company

I experienced the most disgusting service ever tonight at mcdonalds tokai .. firstly i went through the drive thru thinking it will be quick and efficient... but was i mistaken. My partner and I waited 30 to 40 minutes for someone to help at mcdonalds tokai(dont feel like wasting my time using CAPS)

Firstly the lady that spoke over the intercom was disrespectful and wanted to tell me they short staffed... i dont care if you dont have enough staff that is not the consumers problem. And i am a paying customer. Then when i was eventually helped and moved to window 1 there was a black guy serving( me thinking he is training) i asked initially for chocolate milkshakes and then he told me the machine is broken(why the F* do u take my order in the first place so then i asked what zero drinks do they have her clearly states 'We have coke zero, sprite zero, fanta zero and ****** beer zero) i told him give me fanta zero... he say fine.

I get to the third window where u collect the food... and he tells me no fanta zero only ****** beer and coke zero... at this point i am ****ed. I then ask for a manager and some staff says he is the manager and he starts giving me attitude and tells me i am a **** and he didnt say we serve all the cooldrinks. My partner gets upset and tells him that he did say so!!!

I asked for his name and he refused to give his name and told me... you dont need my name.

I HAVE BEEN IN THE SERVICE INDUSTRY FOR MORE THANP 14 YEARS AND I HAVE NEVER COME ACROSS SUCH DISGUSTING AND POOR SERVICE IN MY LIFE...

I WANT A CALL FROM THE REGIONAL MANAGER AS THIS TYPE OF SERVICE IS NOT TO BE TOLERATED BY ANY CONSUMER..

PLEASE THIS IS A WELL KNOWN FAST FOODS AND TO GET THIS TYPE OF SERVICE IS UNBELIEVABLE.. IS I DONT RECEIVE FEEDBACK I WILL TAKE THIS TO EVERY MEDIA PLATFORM...THIS IS NOT A THREAT BUT A PROMISE..
