He uses officina:
Cicero, de officiis I.150
Iam de artificiis et quaestibus, qui liberales habendi, qui sordidi sint, haec fere accepimus. Primum improbantur ii quaestus, qui in odia hominum incurrunt, ut portitorum, ut feneratorum. Illiberales autem et sordidi quaestus mercennariorum omnium, quorum operae, non quorum artes emuntur; est enim in illis ipsa merces auctoramentum servitutis. Sordidi etiam putandi, qui mercantur a mercatoribus, quod statim vendant; nihil enim proficiant, nisi admodum mentiantur; nec vero est quicquam turpius vanitate. Opificesque omnes in sordida arte versantur; nec enim quicquam ingenuum habere potest officina. Minimeque artes eae probandae, quae ministrae sunt voluptatum: "Cetarii, lanii, coqui, fartores, piscatores," ut ait Terentius; adde huc, si placet, unguentarios, saltatores, totumque ludum talarium.
Now in regard to trades and other means of livelihood, which ones are to be considered becoming to a gentleman and which ones are vulgar, we have been taught, in general, as follows. First, those means of livelihood are rejected as undesirable which incur people's ill-will, as those of tax-gatherers and usurers. Unbecoming to a gentleman, too, and vulgar are the means of livelihood of all hired workmen whom we pay for mere manual labour, not for artistic skill; for in their case the very wage they receive is a pledge of their slavery. Vulgar we must consider those also who buy from wholesale merchants to retail immediately; for they would get no profits without a great deal of downright lying; and verily, there is no action that is meaner than misrepresentation. And all mechanics are engaged in vulgar trades; for no workshop can have anything liberal about it. Least respectable of all are those trades which cater for sensual pleasures: "Fishmongers, butchers, cooks, and poulterers, And fishermen," as Terence says. Add to these, if you please, the perfumers, dancers, and the whole corps de ballet.
