Impeccable Customer Service Tip #545
Whenever possible, offer detailed parking instructions to your customers and clients: best entrance, best option of street vs. lot vs. garage, validation/reimbursement instructions, mobile app accessibility for paid parking, time limits, best entrance/elevator from garage, etc. Doing so will help prepare them, ensure punctuality and, subsequently, remove possible anxiety.
