What do you think of a demanding chemo patient who had a bad reaction to the medication in a Publix and demanded the manager get him a bucket? Go throw up in the toilet bowl or outside on the grass. What gall!

I think this a rather strange demand.  It would be much quicker to simply go to the toilet and throw up there.  (Would not advise throwing up in the grass.  This is disgusting and people might walk in it).  I could see asking the manager to call for an ambulance if one was needed though.
