reasonable? what would you do if he didn't come back? Alerted the waitress and waited with them until the police came
If she choked? Shouted for help, tried to help
if a woman turned up and claimed to be the mother? Laid a hand on the child and caused sufficient noise for the waitress to come over and mom finish her wee
for if a different man turned up and said he was the father? See above plus asking the DS.
If the child screamed out "stranger! stranger!" when you tried to speak to them? Stopped speaking to them but continued to observe until Mom got back
If the original man claimed you were trying to abduct his child? Point out I'm clearly sat here with my kid not leaving
If the child had stolen property with them and was being followed by police tell them where the Mom was
If the child had chicken pox or invisible infectious disease? Thankfully she didn't ask me to licl them eh?
If the management said the child had to leave the premises? Tell the child to stay / still them messing until Mom got back
If there was a fire alarm? Tell the waitress and get the child up ready, knowing mom is going to come running
if the child picked up a knife? Be happy they're eating their lunch
If the child wet themselves or soiled themselves? Comfort them until their Mom came back
LIf the child was stealing from other customers? Alert the waitress
If the child dropped and broke a plate? Alert the waitress
If the child fell and broke an arm? If the child was sick? Comfort them whilst the waitress gets Mom
If the child started crying? Try to comfort them and reassure them Mom is coming back
If the child came into contact with an allergen? Alert the waitress
If the child had an asthma attack? Alert the waitress
I could go on and on and on and yet you've missed the important one. The only one that would be really hard os the kid immediately pegging it out the shop. Virtually anything else is easily sorted. In the latter situ, I'd yell at the waitress to watch my kids and I'd go and grab the kid. Which is possibly a ploy of course for the Mom to come out the loo and kidnap my kids because that's really very likely to be the whole ploy eh?
