TM30 and using power of Attorney

I had a first effort at TM30 in Hua hin immigration. 
Experience below may help others to be prepared for requirements.
I already had been told that they require the owner present, so I had to find out.
From experience that is not necessary in bangkok and jomtien if you have the appropriate paperwork.
However TIT, and we have to find out the differing requirements as necessary.
The officer would not accept my TM30 , despite being the resident according to Usufruct and chanote, which must satisfy the legal requirement.
So, being prepared, I gave all the necessary documents for the owner of the house.
But, not enough, the requirement is the owner has to be with you.
So again, being prepared for all that I knew,  I gave the power of attorney from the owner.
I still came unstuck. I was told its not acceptable without the stamps for duty paid.
There is a first time for everything. 
The immigration officer was very helpful stating that its stamps for 30 Baht.
But I cannot get them at immigration. Have to go and get the stamps - Stationary office.
Fortunately I had enough time to go out and get the stamps, but only just.
It was hard to get the nearest stationary store to understand what I wanted.
I got back re-queued again and got the TM 30 cleared with about 5 to 10 minutes before closing.
The form was accepted with the duty paid stamps, hopefully I can save half a day next time.

Lessons learnt. Be aware, and attached may help. Stamps may also be available from post offices.
I attach photo of power of attorney POA form with the stamps. You need 30 baht per person.
I also attach a copy of the POA form, its from about 10 years ago. Tenants in an apartment had no problem using it then. Still ok, but now I needed the stamps.
However I cannot upload the POA pdf and have had to capture it in Jpg, so its cropped to suit
