I'm not a single parent, but my wife is ill and is not often able to care for our 4yo on her own. 90% of the time, if I don't take the kid with me, I don't go anywhere. I don't take my kid to the vape shop, not because I don't want her exposed, but because I don't want the distraction of having to watch/entertain her while I'm there, but if I needed to go and she was with me, I would have no problem bringing her in. I would not hang out for hours though, because at 4 years old, she gets bored quickly and can be quite annoying and I wouldn't want to expose others at the vape shop to her tantrums, someone has to protect the vapers!
