This question should be said to be a matter of opinion. Merchants skillfully use idioms in homophonic ways, some of which are quite lively and interesting, but they dare not compliment them. As you mentioned, "treating the population quickly" is not very good. Besides, even the best things are used too much, and homophones are everywhere, which can be said to be "typo idioms". That will not only make people feel uncomfortable, but also make people feel uncomfortable. I believe that the landlord is also one of the "uncomfortable". To be honest, I'm not feeling well either. However, the merchant did not break the law, but used a rhetorical device, and there was nothing we could do! We can adjust our mentality, appreciate what we like, and let our disgusting things go to hell!
