Question about "The Firm"...

Sorry if this was already discussed somewhere, but I couldn’t find it on a search.

I was watching The Firm yesterday on regular TV (I’ve only watched it a dozen times or so).

I’ve always wondered: If Tammy was underneath Eddie Lomax’s desk the entire time he was talking to the two goons, how did she know enough to tell Mitch later on what they looked like?

Mitch asks her if she knows what they looked like, and she says one had “weird eyes” and the other was “stocky like a wrestler”.
