Customer can be a hand full.

[Spike60]

There are some distinctions between businesses where having the "office in your pocket", (I like the term), and having the office in the office are each appropriate. One is where the service is provided at a customer's location, rather than at a business location. A second is where the service provided cannot be confined to business hours. Both apply for instance in the case of snow plowing. For most of my pro customers, tree servicees, landscapers and such, the cell phone is a Godsend. Keeps them in touch with customers during the day, and eliminates going home to return dozens of phone calls/messages every evening. But in businesses like mine, there's no need for any customer contact when the store is closed. You wouldn't send a text to a restaurant owner when he's closed just because you're dying for the meat loaf special.

The amount of calls/texts that are unnecessary, and the times they receive them, is what my customers complain about most often. Back to snow plowing, one friend sent out a letter to all of his customers pleading with them to refrain from calls/texts during the storm. Takes care of 100 properties, and cannot constantly reply to folks that want some reassurance that he's going to plow their driveway. As with a lot of things, it's the "multipliers" that can make something go from the innocent to the impossible.
