"Please, Just that small modification" - customers: Having a close relationship with your customers is great. Some use it to ask you constantly for little favours. If you fulfill these (for free) with a smile - be prepared for more favours coming up. Much more.

Yes, it doesn't hurt to do an occasional favor for a good, repeat customer. When you do, be sure to include the expense, along with a "customer service credit" on your invoice. The cost becomes more real to them. It makes it harder for them to forget the favor and easier for you to bring it up.
