Selling GME covered calls

I'm wondering if there are any actual disadvantages to selling short term (less than 1 month) covered calls.

They will probably sell 20 to 30 shares of Covered Call with an exercise price of $40, which matures on 6/21. Even if it surpasses that price this week (I think it will), I think it will be short sold to around $30 to $35 next week, so I can buy back even more stocks.

Has anyone experienced this?
