Met a grouchy auntie!

Last friday, we brought deardear to ShopNSave. I went to take a basket and walked over to deardear, who was standing near the cartons of fruits. She was vv excited, grabbed a box of grapes, jumped up n down n babbled non-stop (maybe she's telling me to buy it). At that point, there was a store assistant walking by. She was probably in her late forties n looked vv grouchy. Upon seeing deardear's actions, she said rather loudly n harshly "Aiyo, 等一下掉下来".
Deardear was so engrossed in herself tt she didn't hear it. I did n my mother cub protective instincts went into alert. I was so irritated tt i kinda talked back (rather loudly too) "掉下来就掉下来，又不是赔不起". Normally, i m a person who doesn't like to attract attention, but was so pissed off tt i just blabbed it out. Alan, who was standing a few metres away heard me too, n came over to ask wat happened. The idiot auntie juz walked off. I m not sure whether she heard me, but i didn't care.
