 During the free tasting promotion, the jasmine tea was brewed on the spot, but the time required for brewing was too long for some of their more impatient customers.To overcome this problem, the promotion staff brewed the tea in the office before going to the promotion location and poured the ready-to-consume jasmine tea into big pots and pans.However, this technique did not solve the problem; the tea in large pots and pans spilled over on the way before they reached the location.
