What I would recommend is to be offered drinks, teas etc when the person comes to check in at the front desk. Not for us to ask. To be offered wold be nice.
Also please instal automatic doors. Its a heavy door and I always got to give it a good pull or push.
Lastly install a Disability Ramp. I don't know how the customer can get up the stairs who are in wheelchairs and for people who can't do the stairs.
