I think it's a prime example, if we're fussing over it, maybe the price was too low. That's fine but customers see the price hike and they know what it means, too... The devil may care but it hurts my business, the day the wrong customer starts shooting off at the mouth about this practice... Folks, if a business owner can take it personal, rest assured there's a customer who can do it, too. That is why I found a better way of doing things over the years... Charge appropriately to begin with, give a solid estimate in the first place. Now they can call, cancel, start back up, stop, no start, hey wait, ok and last minute hey can you come by this afternoon?! And I just say "yes sir, yes ma'am" or whatever the case may be... Charge the right price upfront and it's all just another day at work. Because, and it took me years to nail it down, but when you CAN show up this afternoon? You can also be the one guy who charges a little bit more. Simple, don't forget to smile.
