To my knowledge, no, and I visited the shop from 1978 when Tim went on his own from Joss, up until Tim's death.
Tim went on his own in 1978, and later that year as I recall, Bob Frey joined him, as Tim was getting busy. It could have even been early 1979.
Somewhere around the late 80s, or about 1990, Bob Frey went on his own, and Mike Cochran joined Tim, pretty common knowledge. Either during the Frey years, or just the Cochran years, John Slavotnik (sp?) worked with Tim, mostly doing sneaky petes, as I recall.
There was another Bob who worked with Tim, gray heair and moustache, can't remember his last name. If I remember it, I'll edit. He was only there in the Cochran years, and only in the old shop on Georgetown Road, the old meat building. Not in the new place on Leeds Avenue. This Bob only did customer orders, and simple things, like pressing wraps and things like that.
Not once did I ever see Bill McDaniel in the shop, in either location. I can't account for all times, but this is my memory.
All the best,
