It’s a tenuous little dance, customer service. So often waiters bring luggage to the table — and so do customers. Remarks are misconstrued and sensibilities are offended for the smallest of reasons. We all could avoid these moments of animosity if we started with the assumption that people have good intentions. Who put rainbows in my cereal today, you ask? Nobody — in fact, it was quite the opposite.Waiting in line at Fremont Coffee Company, texting on my iPhone, I thought I detected a slight sneer or glare from the barista. Then I noticed the sign above. It made me feel somehow … profiled. I know I’m conscientious about my phone use in public, but he wouldn’t know that. Doesn’t mean he should assume the worst, though, I fumed. The baristas mingled with all other patrons in line, but not me. I admit I can be terse prior to three shots of espresso, but I was pretty sure I was encountering phonism.Then I noticed another set of signs on the espresso machine. Geesh, good morning to you, too, I thought. This is Fremont, right? Center of the mellow, hippie, “Every day is like Sunday” freakin’ universe? The alert level went up to orange.The other barista took my money with a smile and asked me about my sweater. I couldn’t tell if I was being fed the old charm-’em-at-the-end for a tip trick or they were just being nice. I decided on the latter, and began to calm down. Then the first barista handed me my latte, at right. I’ll never know if it was a subtle message or coincidentally cool latte art, but I decided to smile and tell my inner voice to shut the @#$% up. It was a really, really great cup of coffee.Fremont Coffee Company459 N. 36th St.Open Mon-Fri at 6:00 a.m., Sat-Sun at 7:00 p.m.
