I go into your store regularly to sit and read or study. I am not sure why I keep going, because nearly every time I am there, you are playing a radio station that is playing commercials rather than music at least half of the time. Maybe it's just me and my almost attention deficit disorder, but I get distracted anytime there is talking near me. I cannot concentrate on one thing while a conversation is going on around me, when that conversation is as loud as your sound system is. I have, over the years, learned to be able to listen to music with words while studying, but I have not yet perfected these skills when it comes to commercials and talk show hosts.
Now, I do not expect you to change your musical habits because of my (perhaps unique) problem. But, I suspect that most people do not enter into a coffee shop in order to hear someone selling Billy Bob's plumbing services.
Also unhelpful: not having any chai tonight. And when I got a nonfat vanilla latte instead of my chai, I'm pretty sure it was whole milk rather than skim. And, the store was really, really cold.
[Sorry for ranting. I just felt the need to complain.]
