I'm very sorry to hear about your experience. I would suggest for you to send an email to Tim about this at
tcook@apple.com and be polite and professional about it. Just express how you felt. Sure, it's not the end of the world but it did affect your launch day experience for sure.
I sent a feedback to Tim about a particular store launch experience for last year's iPhone 6 and this year they totally raised the bar. I knew Tim read the email because the store manager had a chat with me personally about it. Lo and behold, this year they made the experience so much better for everybody!
I think Tim should know about this as he will forward your concern to the store leader & managers of that store. Trust me, when they get emails from Tim, they get very serious about making it right for you after.
Just make sure to keep it polite and professional and I'm sure it will work out at the end
