  Recently the ALICE collaboration has observed an interesting systematic
behaviour of ratios of identified particles to pions yields at the LHC, showing
that they depend solely on the charged-particle multiplicity in pp, pPb and
PbPb collisions. In particular, the yields of (multi)strange particles relative
to pions, increases with multiplicity and the enhancement is mode pronounced
with increasing strangeness content. We will argue, that such a pattern of
arises naturally in the thermal model taking into account exact strangeness
conservation. Furthermore, extending the thermal model by including hadron
interactions within the S-matrix approach, the ALICE data can be well
quantified by the thermal particle yields at the chiral-crossover temperature,
as previously found in central Pb-Pb collisions.
