Did a leaf clean-up for a regular customer back in November. Been a customer for i think three years, always payed promptly, gave tons of compliments, very nice person no problems ever. Anyways I send a bill for the clean-up the first of December. Due date comes and goes, no check. I didn't think much of it because she is such a propmt payer, and always so happy with everything. I figured invoice probably got lost in the mail, or perhapps never even got mailed first place. So on Jan. 1 I mail a new invoice. No late fee or anything. Check arrives the today along with a note reading. Andy, I am so very sorry this payment is late, I misplaced your original invoice. Please accept my sincere apology, I hope that you can please forgive me. Thank you very much for all you have done. Look forward to hearing from you this spring.
