This ain't the US where tips are a mandatory part. Tipping is 'actively discouraged' by IR, then why do it. Infact, I applaud the OP for complaining to the DRM since they're already paid for doing their jobs[they are paid sufficient in the first place unlike the US whose custom you are trying to copy]. Tipping is an extremely im-perfect system and it had be good if it doesn't increase.
please wait...Translate to HindiYeh US nahi hai jahan tips anivarya hissa hai. IR dvara tips ko sakht manaa kiya gaya hai, phir bhi kyun karein. Asal mein, main OP ko tareef karta hoon kyunki woh DRM ko shikayat karne ke liye pehle se hi bhugtaan karte hain [unhe pehle se hi achhe tarike se bhugtaan kiya jaata hai, bilkul US ki customs copy karne ki koshish nahi kar rahe hai]. Tipping ek atyant adhuro system hai aur agar yeh badhta nahi, toh achha hoga.
