Baba's advice and teachings to each and every one were unique and different. Sai Baba prescribed different rules and observation for different people with spiritual authority.
From Shri Sai SatCharitra Chapter 19. 

Without a bond or tie of the previous birth, nobody goes anywhere

Without a bond or tie of the previous birth, nobody goes anywhere. Therefore, whether a man or a beast or a bird, do not shoo it away contemptuously.
Shri Sai SatCharitra Chapter 19

Not only Myself but also my Tomb will talk and give solace

Not only Myself but also my Tomb will talk and give solace, hope and cheer to those who seek Me as their sole refuge. This I speak in truth. Believe Me ! 

Why should just a nod of their heads by the people in appreciation turn your head?

Why should just a nod of their heads by the people in appreciation turn your head? Rather, it should be your
chosen deity whose heart should melt in compassion and burst out into beads of perspiration!
Sai SatCharitra Chapter 6

Engage yourself in good thoughts and actions

Engage yourself in good thoughts and actions. Do your duties and surrender yourself, heart and soul, to Me.

To serve me, give up differentiation

To serve me, give up differentiation, sometimes I come as dog, sometimes as pig

My guru, after depriving me of everything, asked me for two paise

My guru, after depriving me of everything, asked me for two paise. I gave them to him. He did not want metallic gifts. What he asked for was (i) faith (nishta) and (ii) saburi i.e., patience or cheerful endurance.

Gnana Marga (path of knowledge) is Ram Phal

Gnana Marga (path of knowledge) is Ram Phal. Bhakti Marga(path of love or devotion) is Sita Phal. The pulp of the Sita Phal is almost on the surface and can be assimilated quickly, whereas the pulp of Ram Phal is deeper within and is hard to get at. 

I draw my devotee to me

I draw my devotee to me, at the time of his death, even though he may die a thousand miles away (from Shirdi)

Athithi is whatever creature is hungry and comes to you at the lunch time

Athithi is whatever creature is hungry and comes to you at the lunch time, whether it is a human being or a bird, beast or insect. All these seek food. The real athithi that you get, you do not regard as such ... At kakabali (offering food to crows) time take plenty of cooked rice outside the house and leave it there. Do not shout or call for any creature nor drive any away. Whatever the creature that comes to eat, let not that disturb your mind. You get thus the merit of feeding lakhs of guests!

This is not a mosque. It is Dwaraka. Those who seek refuge in her will never be harmed.
