Mommy Onion saw a promotion of a laser hair removal treatment on a group-purchasing website. The original price of the treatment was HK$2,000 and the current discounted price is only HK$500. Attracted by the discount, she purchased the service.
After arriving at the beauty salon and presenting the group-purchase receipt, Mommy Onion took off all her clothes and wrapped her body with a bath towel according to the staff’s instructions. She then lay on the bed.
At this moment, the beauty salon staff informed her, “The treatment purchased from the group-purchasing website does not include the specialized gel for the treatment. You can purchase it now at a discounted price of HK$1,000 instead of the original price of HK$1,500.” Mommy Onion was astonished and said, “But it was not mentioned on the website that I have to purchase the specialized gel!”
The staff insisted, “Without purchasing the specialized gel, the treatment cannot be conducted.” Without any other options, Mommy Onion purchased the gel eventually.
