Another that I liked to do that may seem kind of flirty, is grab a pice of ice or ball up a napkin or grab a straw (something harmless) and toss it toward the customer when they aren’t looking at you but can see you peripherally, don’t hit them necessarily and not hard, just noticeable.
Mwingine kwamba mimi walipenda kufanya kwamba inaweza kuonekana aina ya flirty, ni kunyakua pice ya barafu au mpira juu ya leso au kunyakua majani (kitu wapole) na kuwatupia kuelekea wateja wakati wao si kuangalia wewe lakini unaweza kuona wewe peripherally, wala hit yao lazima na si ngumu, tu liko.
