Eh? Who is she?I'll have a cup of tea, please.Hey, what do you mean, 'who'!?
She's my customer!This is grandma. She always comes by.Thank you for having me.Ah, would you like some coffee, grandma? Or maybe some tea?Nevermind that!You can't go on like this! You have to do something! Do you want your shop to close down!?Eh?Hm...
But still,I fulfilled my dream of owning my own shop, and that's enough of a reward for me. I would feel sorry if I got any more than this...If I just manage the rest of my savings I can get by just fine afterwards.Sure, coming right up!Hehehe, Reiko-chan, she called me 'Master'! Master! Hehehehe!Master-san, could I get a moist towel?
"Master" is used to refer to the owner of a western-style shop, most often a bar or coffee shop.
