Very Light and Delicious

I've been working at this Thai restaurant for a little over a month now and I always avoid wearing short sleeve shirts because the plates are so heavy and I don't want to look overly jacked (my arms can tend to look very 'cut' according to comments in the past). However, last week was so ridiculously hot, I had to wear a short sleeve shirt.

I should've seen this coming..

One night last week I was holding the dessert tray, made of metal and rather heavy, for these customers and I was telling them that this one dessert is "very light and delicious" and one of the guys says:

"It doesn't look very light.. your muscles are bulging and your veins are popping out like they're about to wrap around your neck and strangle you!"

And all i could even think of to say was "Well, that'd be a problem then, wouldn't it?"

...I mean, what do you say to that?
