佢日日都唔同喎

Sounds not that 煩 jer....

我係驚之後無咗件事, 唔記得入數! 或者, 到時比人坐地起價咋

should not be......

我都相信唔會, 但到時有得炒, 佢話無貨都得, 此終 online ....

you know someone in HK?  If yes, then can buy for u

朋友係有, 但佢地都唔玩呢 d 野, 叫佢地都未必買到啦

係喎 ben, 一句日文都唔識, 可唔可以日本自由行?

Of course you can.  But I will suggest you to go to Tokyo, because more people can speak English.  If you go to Kyoto, then you may need to speak a bit Japanese.  But anyway, you won't die if you can't speak any.  Ha Ha Ha.  Use your body language.
