German Vocab That Makes My Life Easier

Ironically, the German vocab that makes my life easier is not German vocab that I've learned in my Intensive German course, but German vocab that I've learned while out and about.  Here's a list of some German vocab that makes my daily life so much easier:

• "Alles?"  As in is that all (used when shopping)
•  "Hier oder zum Mitnehmen?" Here or for takeaway ( a special thanks to the lady from Starbucks who patiently taught me this German vocab :)
•  "Brauchen Sie eine Tasche?"  Do you need a bag? 
•  "Welche Größe?" Which size, to which the correct answer is either"  "klein", "mittler"  or "groß"
• "Drucken" or "Ziehen" "Push" or "pull" - very handy German vocab to know when reading the sign on doors
• "Ich möchte zehn SchinkenScheiben des Schinken bitte."  I would like ten slices of ham please.  I was thrilled to have learned this German vocab last week as it now means that I can order the good stuff from the deli and not just buy the mediocre packaged stuff!

I realize that none of this German vocab is mind blowing, but it's such a relief to actually understand what someone is asking me, and being able to respond, rather than just giving them a blank confused stare.

Next on my German vocab list is mastering money.  I know my numbers but when I go to pay and the cashier hurriedly tells me my total is "fünfundzwanzig Euro und dreiundvierzig Cent", (25.43 euros) I freeze, and my comprehension of German vocab goes out the window so I just round up the number.  As a result, my purse is bursting with loose change.  I took  a handful out and put it on our table while J.P. stared in disbelief asking what I was going to do with it.  I calmly told him my dilemma and that since he didn't have the same problem as a fluent German speaker, he should take it and try and use it.  Needless to say he didn't see this as a longterm viable solution, and the coins are still on our table (although he did neatly stack them).  So I guess it's time for me to master my currency German vocab.
