Large White?

What do you think of when you think of a large white? A shark right?! According to my brother and my dad its milk. Ok, so my family and I were at this restaurant and the waitress asks us what we want to drink. Mom says "I'll have a large ice tea." I say "I'll have a large white milk." Tyler and Dad says "I'll have a large white." That makes no sense! It sounds like they are ordering a shark! You know? The great white shark? Yeah. I found that very odd when they said that. So my only advice for at a restaurant is 'Always clarify by saying large white milk not large white.'
