Should I have...?

I witnessed this scene today:

- Old Uncle wanted to try bubble tea(no joking)
- Counter Girl suggested oolong tea(sensible)
- OU paid for drink (as he should)
- OU then requested to break his $10 into 5 x $2 notes (trying his luck)
- CG obliged (not bad service)
- CG realised not enough $2 notes in the cashbox, returned the $10 and apologised(reasonable)
- OU became angry and shouted at CG to return change of $0.10 (uncalled for)
- CG replied she did so earlier (unfortunately i was busy on my phone to actually see her giving back change)
- OU got agitated and called CG stupid and threw the receipt at her(plain rude)

I was 1 arm's length from the whole scene...and throughout that 5 mins, i was wondering if i should interfere..

I could have told OU that CG already returned the change but i hesistated as i really did not witness the returning of $0.10 change..or i could stand up against OU calling CG names - i really don't like this..raising voice i can still give the benefit of doubt that one has a loud voice..but names calling..tsk..

Also, i was feel a little lousy these couple of days and i really have no intention of getting into another argument, esp when i'm not directly involved(i got into an ' argument' with a condo security guard the day before and he actually called up my friend - the resident, to complain about me)

I'm usually quite mild and occasionally have been labelled 'pushover'...but the 5% when i erupt..you wouldn't want to be near me..

Sorry CG.. -.-

Would you rather be first..or..last?

Do you feel honoured when someone puts you as 'first line of defence'..ie. you're the first person that comes to mind when tat someone needs help..

Or..

Do you feel honoured when someone puts you as 'last line of defence'..ie. you're the last person tat he/she will approach after exhausting all other means, as he/she has superior faith in you that you will not fail him/her..

**********************
Do you take someone for granted when he/she is the 'first' since..well..he/she is the 'first' to be activated..

Or..

Is it when you put him/her as the 'last'..since it is assumed that this person will definitely, confirmed, guaranteed be able to rescue you..
