Platinum client

In theory, only the most important, strategic clients of the firm are platinum clients: That five percent that accounts for ninety percent of the firm's revenue.

But, on the lips of any salesperson, however, it means my client: the particular client — or client prospect — in contemplation at that very instant, however tawdry, pissant or strategically irrelevant.

Particularly when it has just said “all our other counterparties have agreed this”.
