I tried out a Bitcoin ATM for the first time. Unfortunately, it will also be the last time. The Bitcoin being sold was marked up an additional $2000 above the market price. I bought $20 worth of Bitcoin, but with the high mark up it ended up being only $8.60 worth of Bitcoin. Conclusion: Double check the market value for the day before buying Bitcoin from a Bitcoin ATM. Otherwise, just avoid these things at all costs. When you buy Bitcoin directly on the exchange, your fees will be under 1%.
