A Starbucks barista said "You should leave here" so I had to leave a Starbucks shop in Munich. Though Starbucks Deutschland and I planned that a shop manager will either apologize me or explain me, the manager has been ignoring me since May 6. I've been uncomfortable since the barista's words, it's sometimes difficult to breath. I'm down these days.
I attached an email from me to Starbucks. This accident was happened to me. Please help or indicate what I should do.

To Starbucks,

My name is Yoshida, an Asian person, I live in Munich, Germany.

I went to your shop in Munich on March 2. While I was in your shop, a caucasian female customer had her personal speech inside your shop around 10 minutes for 5 other customers and a Starbucks barista who is also a caucasian female. After the speech, the barista, Ms.Flieschmann, said to me "You should leave here." so I had to leave your shop. I did nothing, I was just there, but Starbucks kicked me out. There was no explanation. Though I understand only a few German, there was a suspicious issue against race and culture difference in the customer's speech. And when I left your shop, Ms.Flieschmann explained me which actions are OK in Germany and which actions are not OK in Asia with repeating "In Germany", "We are" in English.

I complained this problem to Starbucks Deutschalnd on March 6 by email. But no reply. I called them on March 21, 28 and April 1. Finally on April 1, Ms.Stoppa in Starbucks Deutschland Essen office emailed me back "sorry" and we planed that I will meet the shop manager and the manager will explain me or apologize me about the problem.

It passed more than 2 months since the accident. I still can't meet the shop manger, Ms.Kindall, yet. I hope she will re-schedule soon, because I've been uncomfortable for more than 2 months and every time when I pass through your shops in Munich. When Ms.Kindall emailed last week that she can't meet me unless I don't go to a shop where is far and no relationship from the shop where the problem occurred, I was shocked, very uncomfortable and difficult to breath.

If Starbucks had a reason why you refused me to stay inside your shop, sure, I'll listen to your reasons and re-think about my problems. But if a stereotype/prejudice helped you to kick me out, I require you to apologize me officially properly. And I don't want you to allow any customers to have personal speeches inside your shops. I've been uncomfortable for 2 and a half months. If your shop manager can't meet me this week, I'll take another actions. Thank you, regards,
Yoshida
