Lithium

Buying ice cream with twenty-nine choices on my first visit to Rostock, Germany
I could see what I wanted; but couldn't find the shop that sold it: I'd lurk at the back of lines, only to discover the retailer serving liquor or bratwurst mit einen kaiser. I tried following people around who held the desired delight, but couldn't muster the nerve to ask: Wo finden Sie es? I was too tired to deal with all that miscommunication entailed.
After walking up and down blocks of stores displaying beach toys and sport clothes and kaffee, I spied one with a long line, a sign out front with pictures of cones and cups filled with neon-colored ice cream, and corresponding prices. Viola!
Ja. I'd found my longed-for treat. As I neared the front of the line, I craned my neck to decipher the flavors before I had to pick one. Vanille, schokolade; pfefferminze, nougat; walnuss, haselnuss, whisky krem, and all sorts of berries.
My turn.
I point, not remembering the word for dish, open my mouth, and promptly start speaking Thai. Kaw nung... oops. Wrong language. Dang. I smile and hold up two fingers.
She asks if I want two scoops. I can understand that. Yes. Whisky krem und nougat.
New-ghat?! She quizzes. I nod my head. Plop goes a scoop of chocolate-looking soft ice cream.
Nein, nein. Ist das schokolade? I ask. Waving my hands back and forth in front of me. No schokolade, bitte.
The clerk squints at me, thinks about removing the scoop, but realizing it's already melted into the whiskey cream portion and cannot be separated, frowns.
Nur whisky krem, I say.
With an annoyed sigh she grabs a new cup, dishes me a new scoop and bangs it on the counter. I place 50 euros on the money plate and she returns 47.50 back to me.
I walk away dissatisfied with the exchange, vowing to be more patient with myself and others in the future.
I don't even like whiskey.
