The addition of "retail staff" here surprised me.
I'm a techie who took a break from tech and startups the past few months to help out my S.O., who owns a retail store. I worked the front counter, ran inventory, etc. for the past 3 months.
I had never worked retail before. I got into tech at an early age and skipped most of the "menial" jobs that typical American teenagers have. So working retail was eye-opening for me.
Retail workers get paid shit wages to deal with your crap. Yes, you. Whatever crap you've been dealing with, we have to take it with a smile and help you out. I've stood behind a counter and listened to a homeless guy ramble about anything and everything for 12 minutes (I had a small clock within view.)
Your attitude in this post indicates to me that you could probably use a bit of this type of work yourself. If you think it's beneath you, doubly so.
If you're curious what it's like for a techie/introvert/successful entrepreneur to work retail, I've been blogging about it. (Blog link in my profile) To be honest, the 3 months I spent there made me a far better person than any given 3 months I spent in the tech industry (I've run tech companies for 14 years now.) It humbled me, and gave me far more respect for my fellow human beings. And I learned there's nothing like the priceless joy in someone's eyes when you do something for them and can see pure joy radiate from them. I hope you, too, can experience this.
