"My dear Maxie,
I would like to give immediate notice on my storage unit at your facility. The unit has served me very well & I have enjoyed great service from your superb gate staff Agrippa, Elson & I forget the other gentleman's name.
Thank you also for always being so obliging Maxie. Every time that I needed to let someone in, I simply called your number & you were always a great pleasure to deal with, & nothing was too much trouble for you.
Should I have storage needs again in the future I shall head straight back to you. The company is lucky to have you!
