Yes man, I know how that feel. I remember last time that happened to me:
Drunk girl: Hi, can you play "despacito".
Me: Sorry, I dont have that tune.
DG: But you have computer, you can find it on youtube.
Me: But I don´t have wireless connection
DG: I can find it on my mobile phone.
Me: I can´t play it from your phone, I dont have the cable to plug it.
DG: Yes you can, I have a cable to plug my mobile to your mixer.
Me: ......shit
