Another pearl from Manfred.  Hiya mate, hope you are well!

Many people don't know how to hand-over-hand bond their path in front of
their movements, or else they don't have the level of forward-planning
and thinking that is required to automatically do it.  Basically, you
never move the vulnerable component to a new area unless your spare hand
has touched it first.  So you would pick up the static-free bag with the
component already bonded to the bag, and now you have bonded your body
to the bag and component - at this point you can safely take the
component out of the bag, AND safely put that component down on some
conductive surface PROVIDED you bonded yourself to said surface by
touching it first with your free hand, and so on.  Hand-over-hand
bonding.  For those people whose brain cannot be trained to do this
automatically - buy a bonding strap with a high-value resistor in it.
