What does Mr. Lorry think of Jerry’s second “occupation?” (From Book 3 Chapters 6-10)

Lorry is shocked and angered upon hearing about Cruncher's second occupation.

"My mind misgives me much," said Mr. Lorry, angrily shaking a forefinger at him, "that you have used the respectable and great house of Tellson's as a blind, and that you have had an unlawful occupation of an infamous description. If you have, don't expect me to befriend you when you get back to England. If you have, don't expect me to keep your secret. Tellson's shall not be imposed upon."
