What are the differences?

I never expect to have 'close shop' meal from my department. However, my boss able to get one for our own division, a table for 8 person. We went Restaurant Chui Heng to have dim sum and 'yee sang' .

This is not the main point of my title mentioned. After we had our lunch, we were asking for dessert, as per conversation below: (funny part please refer to chinese characters) from my AD.

"今日有么耶甜品啊？"
What do you have for desserts today?

"西米露，雪蛤膏，红豆沙，。。。。。。。。"
Sago, hasma, red bean etc

"红豆沙好热吗？我赶时间."
is the red bean soup hot? coz im short of time.

"是，热的。"
ya, its hot.

"好鬼热的？"
izit damn hot?

"............"
speechless

Point: What is the difference between "好热", and "好鬼热" which the waitress really dunno how to answer my AD.
