Wow... for that price I think the price is reasonable for the fact the prawns seemed to look like mini lobsters from your photos, but still too expensive for me. 😅
(But then again, buying back home with the same ingredients could cost more plus prepping)
Good for you that your client allows you such a window opportunity.
Itchy mouth, eat vegetables or japanese cucumber (sweeter then locals) with no dressing lor. Pao minimal calories. Hahaha.
