a froth provoking experience

First I give you all permission to laugh at my ignorance.

Well, today I went to a coffee shop for the first time ever. My grandpa is staying with us for two and a half weeks while my grandma is in New York. He had a dermatologist appointment today because he had skin cancer on his face removed and went to have stitches out. When he was there they said that his glasses were leaking copper into his face and that they needed the nose part to be replaced. We took him over to fix his glasses (which they also sonically cleaned) and they said it would be about 20 minutes. My mom suggested walking over to City Brew across the street, so we went.
We walked in and it looked cool. Very what I would expect a coffee shop to look like. My mom and grandpa ordered just a coffee, but if you know me I'm more of the sweet type. My experience with coffee is limited to Costco Latte' Freeze, those Starbucks cold sweet things you can get at supermarkets, and embarrassingly McDonald's iced coffee. So I look at their board and feel overwhelmed. I know I want something sweet, but what is the difference between a cappuccino or a frappucino, and will it taste anything like what I'm used too?
I'm feeling on the spot, the nice looking girl is starting to look not quite so nice and the person behind me is getting impatient. I suck up my pride and ask her "what is the difference between a Latte' and a cappuccino?" She says something about frothed milk in the cappuccino, so I say I'll take that. She asks what name to call and my mom says "Megan". I ask why. Dumb question, let's just say I get um..... blonde in stressful situations. So we all go sit down and I'm seeing these people walking around with these really yummy looking coffee, whipped cream, very light and sugary looking goodness. I get kind of excited. Maybe it will be really good? The lady calls my name. I don't hear her, she starts walking over to the table, I see her and stand up to get it. Humm, it's in a foam cup not a clear plastic one. First clue. I open it up and see all this frothy stuff, of course being me I dip in my finger and try it. It taste like... nothing. I try again and it barely taste like milk. I put the lid back on and take a sip and burns my tongue. So, I let it cool, wondering about what it might taste like.
My mom asks to try mine and after taking a sip proclaims "It tastes like dirt". At this point I'm feeling protective of my cup of unwonderfullness, and tell mom that it does not taste like dirt and she just has to let it cool. We sit there awhile and then leave. I still really haven't tried it yet. By the time we get grandpa's glasses and head for the car it has finally cooled enough to drink. It tasted like coffee, not really the flavor I was looking for. I drank the cup but I am unimpressed (the flavor did resemble that of dirt).

Overall I went into my first coffee shop, had my first "real" coffee, and next time I think I will just ask for the sweetest thing they've got.
