customer service

Yesterday I strayed into a pharmacy. Let me say I actually intended to buy some supplements but didn't really have enough cash on me. So I thought I might find out the cost anyway. I walked to the counter and inquired about the supplements I wanted. With the biggest smile she could find the girl behind the counter attended to me and went ahead to pull out one box of  the item I wanted. Just then, her phone rang and by reflex she answered the call. I could tell it wasn't the kind of conversation one would like in the midst of serving a customer. She got angrier by the second and kept pounding what would have been her fist on the counter. Now, remember she still held the box of supplements in that very hand she kept hitting the desk with. I imagined by now, what should have been tablets was powder. I stealithly slipped out of the pharmacy and continued on my way.  I was not ready to take supplement powder home, oh and did I mention that I actually didn't have the cash to buy it either?
