Vape shops sell addictive products and they have minimal overhead. I think the markup on a lot of what they sell, especially the more grey market stuff like nitrous oxide "whip cream chargers" and poppers, is quite high.

A lot that I see have extremely cheap-looking fixtures and little to no decor, and unlike virtually any other store, they stock what they stock, which is generally the same as every other vape shop, and don't even bother to fill out the entire space if it would hold more merchandise.

I assume some are able to negotiate lower rents in exchange for short term leases while the store is technically still on the market for a long-term lease, similar to a pop up store. A lot that I've seen could be shut down, with all the merchandise and equipment loaded into a UHaul, within a few hours if necessary.

Nail salons are similar. They really should have custom ventilation systems since they're working with paints and solvents and glues and nail drills/lathes, but this seems to not be enforced since they're seen as girly little spas rather than industrial workshops and are often staffed by poor immigrants.

Outgoings are different - cheap/dodgy imports, and modern slavery (nail salons are infamous for this) mean that their outgoings can be much lower than other shops. There’s also the tax avoidance many of these businesses partake in, both in the traditional cash-in-hand-business fashion, and the more modern(?) “American Candy store” way (https://www.bbc.co.uk/news/uk-england-london-61777445)

They sell fairly space-efficient, expensive products or services. Generally speaking, the higher you push rent per square foot, the fewer types of businesses you can operate, because people and products take up space and have throughput limits. Nail and beauty services can get spendy fast.

The US has something similar going on with medical and dental offices for the same reasons.

They can’t. They tend to turn over like the rest. But as others noted, their low upstart costs makes them the more likely tenant out of other busines models on the sidelines seeking rent.

We all want little cutsey shops and such but how much money for that is actually sitting on the sidelines at any given time ready to pounce? Hardly any at all, if any. Nail shops and other bullshit on the other hand? There’s private equity specialized in selling shares of these schemes.

They sell something that doesn't work so well online or at a supermarket. Ditto barbers, phone repair, or whatever racially-coded tabloid bugbear de jour. They work in a town centre, everything else can't beat the prices set by larger (often American-owned) businesses.

You can buy a vape online, but as a smoker, you don't want to wait a day when you've run out. Also as a smoker, I don't get why they're not regulated like tobacco. They shouldn't be sold alongside sweets, and should otherwise be treated like cigs (e.g. on packaging, licensing, advertising etc.). Seems very low-hanging legislative fruit.

They're great for money laundering.

Who's to say how many clients a nail bar had? A box of fake nails is easily dumped in the bin.

Surface area needed is much smaller than most other shops.
