  We denote by $\text{ex}(n, H, F)$ the maximum number of copies of $H$ in an
$n$-vertex graph that does not contain $F$ as a subgraph. Recently, Grzesik,
Gy\H{o}ri, Salia, Tompkins considered conditions on $H$ under which
$\text{ex}(n, H, K_r)$ is asymptotically attained at a blow-up of $K_{r-1}$,
and proposed a conjecture. In this note we disprove their conjecture.
