I posted on the other thread but pleased to say I have lots of examples for this one.
The most significant was when I was flying to Athens on my own for a hysteroscopy (i didn't qualify on the NHS in our area as I already had a child and it was much cheaper to go abroad. I was very nervous not least because I had to pay the hospital in cash so I had a couple of thousand euros secreted amongst my clothing. My appointment was at 6am next day so I'd booked a hotel room in bookings dot com.
I changed planes in Switzerland and on the final leg I sat next to a banker (greek but worked in Switzerland). We got chatting and he was horrified to hear where I was staying - a very dangerous area apparently where tourists were often robbed at knifepoint. He insisted he would find me somewhere safer and when we landed he made a few calls, gave me details for a "very affordable" hotel right next to where I would get off the coach which transferred from the airport into the city centre and where I could easily get a taxi the short distance to the hospital. He said he and his brother had been born in the maternity hospital where I was having my op! I thanked him and we parted ways. I got the coach, found the hotel and was greeted by the concierge who told me that my benefactor had already settled the bill in full! I was so grateful!
I left a generous tip for the concierge and emailed my good samaritan once home offering to repay but he said no need, he was just glad I'd been safe and all had gone well. (I did manage to have another baby after that op too!)
I do wonder if I was foolish to trust such a total stranger as i could have "walked into a trap" and ended up robbed, raped and murdered!
Also in Greece another time my 5 year old got his arm trapped in a revolving door of a bank (his fault/my fault for not watching). Bank manager rushed over and offered to drive us to hospital for an xray and a passer by stopped and did some first aid checks to establish if there was a fracture (thankfully not).
In France me husband and child walking back from town to our campsite when the heavens opened - full on thunder and lightning. A lady stopped and insisted on giving us a ride. She even strapped our son into a child seat. We saw her a few days later on the beach and offered to get her and her children a drink/ ice cream but she waved us away saying "it was nothing".
In uk this time. Was going to a job interview/assessment day. Location was an industrial estate some easy from the station. I'd bought ticket in advance and it was only when I got to the destination and that I realised I'd left my purse in my gym bag ... at home. It was before everyone had mobile phones so I couldn't even call the firm to explain. I was panicking and a stranger came over to see if I was ok and I blurted it all out. He was getting a taxi to the same estate and gave me a lift. I had my cheque book ( this was a long) time ago and offered to write one out for my share but he said no, it was fine and then joked her hoped they wouldn't assess my organisational skills! I didn't get the job but always remember his kindness. Luckily the firm provided taxis back to the station or I'd have had a looong walk!
I do try and help other people when I see the opportunity but the gestures seem to be less grand - helping people with buggies etc.
