What on earth is this occupation?

Hello.
This is from the 1865 Post Office London Directory. The person is Ambrose Miller and his occupation looks like Dolly's coml.hot
You can perhaps imagine what sites were suggested when I googled this!
Ambrose was, around this time, a coal factor.

Commercial hotel

I agree - Commercial Hotel

An 1840 newspaper reference to DOLLY'S COMMERCIAL HOTEL, Queen's Head Passage, Paternoster Row, LONDON describes it as having a central and airy situation and as a desireable House for Professional as well as Commercial Gentlemen during their stay in London.

This ad appeared in Durham newspapers from August 1865 until June 1866

Ambrose was, around this time, a coal factor.

He was a hotel keeper in the 1861 census

So were there two Ambrose Millers?

In the 1871 census there's the coal agent in Hackney, born Durham circa 1818, and there's the retired innkeeper in Monkseaton, born Durham circa 1820.

Thank you everyone. That clears things up.
Ambrose, like his father, was a brewer as well as a hotel owner and coal factor (mainly in the 1870s).
Yes, there were two Ambroses, uncle and nephew, although the uncle died in 1828. There were other Ambrose Millers floating around some of whom would be related.

He ended up in Queanbeyan in Australia, dying there aged 91.
And no, I'd never heard of it, don't know how to pronounce it and don't know how he ended up there.
