If they do sales and marketing, they do. Premium tea shops will try to upsell customers all sorts of paraphernalia to prepare tea "just so" and rare expensive teas that taste nearly indistinguishable from less expensive varieties (particularly to randos with sub-sommelier level palates).

If it's just a chill little tea shop that doesn't advertise or go crazy on social media, focuses more on good tea and a comfortable space, keeps things affordable without trying to upsell or be pretentious, then lucky you. Those sorts of lifestyle businesses are very rare these days, they're being outcompeted by predatory hyper-efficient modern businesses to the detriment of all.
